Create a Machining Process for Prismatic Features

This task shows how to create a Machining Process (MP) dedicated to machining a Prismatic Machining Area including rework operations. The objective of the MP is to machine a prismatic pocket by:

● a roughing stage using a Pocketing operation

● a channel rework stage using a Pocketing operation

● a corner rework stage using a Profile Contouring operation

● a finishing stage using a Profile Contouring operation.

Start the Prismatic Machining workbench.

1. Display the Machining Process view and create a Machining Process .

Insert the following operations:

2. In the Knowledge Advisor workbench, use the Parameters Explorer icon to create a "RoughingRadius" length type parameter for the "RoughingPocketing" operation.

In the same way, create a "MacroRadius" length type parameter for the "FinishingProfileContouring" operation and set the value to 3mm.

These user parameters will enable you to set manufacturing parameters such as the "RoughingRadius" for the rework stages or the "Approach and retract tool path radius" for the finishing stage.

3. In the Prismatic Machining workbench, create a Prismatic Rework Area feature .

Set the "Tool radius" corresponding to the roughing radius before the rework stage to the "RoughingRadius" parameter of "RoughingPocketing" by using the Edit Formula contextual command inside the field.

Check that the feature is included in the Manufacturing View .

Note: If the "ToolRadius" parameter is set to 0.0, it will be automatically computed when the machining process is applied.

4. Edit the "RoughingPocketing" operation in the Machining Process View and set "Offset on Contour" to 1mm.

5. Using the Edit Formula contextual command on "RoughingPocketing", set the "Roughing Radius" to half the End mill Nominal diameter which will be found when the MP is applied.

6. Edit the RoughingPocketing Tool Query: ● Set the Tool Diameter to be greater than 10mm.

● Set the Cutting length to be greater than the Depth of the "Prismatic Machining Area" feature which will be selected when the MP is applied.

● Choose the repository file for the Tool Query: ToolsSampleMP, for example.

7. Edit the "ChannelReworkByPocketing" operation in the Machining Process View.

Select the previously created Prismatic Rework Area using the combo.

Edit "Offset on Contour" using the Edit Formula contextual command, and set it to the same parameter of the "Roughing Pocketing" operation.

Note: If no Rework Area feature is assigned to a Pocketing operation identified as Channel, Corner and channel, or Channel rework, a new Prismatic Rework Area will be created when the MP is applied.

In this case, the "ToolRadius" parameter will be automatically computed and equal to half of nominal tool diameter of the operation which precedes the first operation referencing this Prismatic Rework Area.

8. Edit the ChannelReworkByPocketing Tool Query: ● Set the Tool Diameter to be less than 10mm.

● Set the Cutting Length to be greater than the Depth of the "Prismatic Machining Area" feature which will be selected when the MP is applied.

● Choose the repository file for the Tool Query: ToolsSampleMP, for example.

9. Repeat the Edit Operation and Tool Query steps described above for the "CornerReworkByProfileContouring" operation.

10. Edit the "FinishingProfileContouring" operation in the Machining Process View.

In the Stepover tab page, set the Number of paths to 2.

Edit the "Distance between paths" parameter using the Edit Formula contextual command, and set it to the "Offset on Contour" of "RoughingPocketing" divided by the Number of paths.

In the Macro tab page, assign a circular path on each macro, and set each "Radius" parameter to the "Macro Radius" parameter using the Edit Formula contextual command in the Edit Parameters pop-up.

11. Using the Edit Formula contextual command on "FinishingProfileContouring", set the "MacroRadius" to a quarter of the End mill Nominal diameter which will be found for this operation when the MP is applied.

12. Edit the FinishingProfileContouring Tool Query: ● Set the Tool Diameter to be less than 10mm.

● Set the Cutting Length to be greater than the Depth of the "Prismatic Machining Area" feature which will be selected when the MP is applied.

● Choose "Document" as repository file.

13. Click Close in the Machining Process View to store the machining process.

Simulation at

Select the desired option to perform material removal simulation at either Program or Part Operation level. Depending on the selected level, simulation begins either from the start of the manufacturing program or from the start of the Part Operation. Best performance is obtained with Program level.

By default, the Program level option is selected.

Video

Stop at tool change

Select the Stop at tool change check box if you want the Video simulation to stop each time a tool change is encountered in the program.


Collision detection

Select the desired Collisions detection option to:

● ignore collisions during the Video simulation

● stop the Video simulation at the first collision

● continue the Video simulation even when collisions are detected. In this case, you can consult the list of collisions at any time during the simulation.

Best performance is obtained when collisions are ignored.

By default, the Ignore option is selected.

Touch is collision

Select the Touch is collision check box if you want touch (or contact) type of collision to be detected.


Multiple Video result on program

Select the Multiple Video result on program check box if you want to store video results on more than one operation in the program.

● Transparent: to display a transparent bounding box

● Wireframe: to display a wireframe bounding box

● None: if no bounding box is required.

By default, the Wireframe option is selected.

Select the check box to compute all information at the picked point.


Best performance is obtained when Fault box is set to None and the Compute all information at picked point check box is not selected.

Performance

Tool and faceting

There are three methods of tool faceting used in Video simulation: Standard, Smaller and Larger. The number of facets for a tool representation is determined by the chord deviation that is set for the tool diameter (0.005% of the tool diameter).

● Smaller: The picture shows a rough approximation of a tool with six facets. Note that the chord deviation is always inside the actual circle, and that the points are always on the circle (accurate).

This is the most accurate method for the Arc through Three Points command.

● Standard: The picture shows a rough approximation of a tool with six facets. Note that the chord deviation is partly inside and partly outside the actual circle, and that the points are not always on the circle.

This is the best method for material removal simulation. However, this is not suitable for the Arc through Three Points command.

● Larger: The picture shows a rough approximation of a tool with six facets. Note that the chord deviation is outside the actual circle, and that the points are not on the circle.

This is not suitable for the Arc through Three Points command.However, it can be useful for gouge detection.

By default, the Standard option is selected.

Photo resolution

Best performance is obtained when the Photo resolution is set to 0. In this case, a detailed simulation of a portion of the part can be obtained using the Closeup command.Increasing the resolution improves machining accuracy and gives a very detailed simulation. However, this requires increased memory and computation time.

By default, this resolution is set to 0.

Tool axis interpolation angle (5-axis only)

Specify the maximum angle that the tool axis is allowed to vary between two consecutive points. Best performance is obtained for an angle of 10 degrees. Decreasing the angle improves the precision of the simulation. However, this requires increased memory and computation time.

By default, this angle is set to 1degree.

Optimized rendering for Video

Select the Optimized rendering for Video check box to obtain an optimized rendering that improves Video simulation performance.Otherwise, more realistic colors are obtained with a slightly degraded performance. Milling, drilling, and turning operations are supported .


Color

Set the tool (and associated machined area) color to be the same as or different from the last tool, or have different colors for all tools. Best performance is obtained with same colored tools.

By default, the All different option is selected.

Assign colors to the different tools using the associated color combo.

Assign colors to tool holders, parts, and fixtures using the associated color combos.

Positioning Move

Set the Maximum tool axis variation that is to be allowed between the end point of an operation and the start point of the next operation. If the tool axis varies by an amount greater than the specified value, then the tool is positioned at the start of the following operation.

By default, this angle is set to 1degree.

Pocketing OperationsThe information in this section will help you create and edit pocketing operations in your manufacturing program.

Select the Pocketing icon then select the geometry to be machined .

A number of strategy parameters are available for defining:

● machining criteria

● radial stepover conditions

● axial stepover conditions

● finishing

● high-speed milling.

Specify the tool to be used , NC macros , and feeds and speeds as needed.

Pocketing Strategy Parameters

Pocketing Machining Parameters

Tool path styleIndicates the cutting mode of the operation:

● Inward helical: the tool starts from a point inside the pocket and follows inward paths parallel to the boundary.

● Outward helical: the tool starts from a point inside the pocket and follows outward paths parallel to the boundary.

● Back and forth: the machining direction is reversed from one path to the next.

Direction of cutSpecifies how milling is to be done:

Climb milling or Conventional milling

In Climb, the front of the advancing tool (in the machining direction) cuts into the material first

In Conventional, the rear of the advancing tool (in the machining direction) cuts into the material first.Machining toleranceSpecifies the maximum allowed distance between the theoretical and computed tool path. Fixture accuracySpecifies a tolerance applied to the fixture thickness. If the distance between the tool and fixture is less than fixture thickness minus fixture accuracy, the position is eliminated from the trajectory. If the distance is greater, the position is not eliminated. CompensationSpecifies the tool corrector identifier to be used in the operation.

The corrector type (P1, P2, P3, for example), corrector identifier and corrector number are defined on the tool. When the NC data source is generated, the corrector number can be generated using specific parameters.

Pocketing Radial Stepover Parameters

Radial modeSpecifies how the distance between two consecutive paths is to be computed:

● Maximum distance between paths

● Tool diameter ratio

● Stepover ratio.

Distance between pathsDefines the maximum distance between two consecutive tool paths in a radial strategy.

Percentage of tool diameterDefines the maximum distance between two consecutive tool paths in a radial strategy as a percentage of the nominal tool diameter. Depending on the selected Radial mode this value is used as

either Tool diameter ratio or Stepover ratio .

OverhangAllows a shift in the tool position with respect to the soft boundary of the machining domain.

Avoid scallops on all levelsSpecifies whether or not the distance between paths can be adjusted by the program in order to avoid scallops on all levels.

Don't avoid scallops: Avoid scallops:

Truncated transition pathsEnables the tool to follow the external profile more exactly by allowing the transition portion of the trajectory to be truncated (for pocketing using a Back and Forth tool path style).

Not truncated: Truncated:

Contouring passAllows a final machining pass around the exterior of the trajectory and islands for removing scallops (for pocketing using a Back and Forth tool path style). Contouring pass ratioFor pocketing using a Back and Forth tool path style, this parameter adjusts the position of the final contouring pass for removing scallops. This is done by entering a percentage of the tool diameter (0 to 50).Always stay on bottomWhen machining a multi-domain pocket using a helical tool path style, this parameter forces the tool to remain in contact with the pocket bottom when moving from one domain to another. This avoids unnecessary linking transitions.

Pocketing Axial Stepover Parameters

Axial strategy modeSpecifies how the distance between two consecutive levels is to be computed:

● Maximum depth of cut

● Number of levels

● Number of levels without top.

Maximum depth of cutDefines the maximum depth of cut in an axial strategy. Number of levelsDefines the number of levels to be machined in an axial strategy. Automatic draft angleSpecifies the draft angle to be applied on the sides of the pocket. BreakthroughSpecifies the distance in the tool axis direction that the tool must go completely through the part. Breakthrough is applied on the bottom element, which must be specified as soft.

Pocketing Finishing Parameters

Finishing modeIndicates whether or not finish passes are to be generated on the sides and bottom of the area to machine. There are several possible combinations:

Side finishing can be done at each level or only at the last level of the operation.Bottom finishing can be done without any side finishing or with different combinations of side finishing.

Side finish thicknessSpecifies the thickness of material that will be machined by the side finish pass.

Side thickness on bottomSpecifies the thickness of material left on the side by the bottom finish pass.

Number of side finish paths per levelSpecifies the number of side finish paths for each level in a multi-level operation.

This can help you reduce the number of operations in the program.

Bottom finish thicknessSpecifies the thickness of material that will be machined by the bottom finish pass.

Bottom thickness on side finishSpecifies the bottom thickness used for last side finish pass, if side finishing is requested on the operation.

Spring passIndicates whether or not a spring pass is to be generated on the sides in the same condition as the previous Side finish pass. The spring pass is used to compensate the natural spring of the tool. Avoid scallops on bottomDefines whether or not the distance between paths can be adjusted by the program in order to avoid scallops on the bottom. Available for single-level and multi-level operations with bottom finish pass. Compensation outputAllows you to manage the generation of Cutter compensation (CUTCOM) instructions for the pocketing operation's side finish pass.

The following options are proposed:

● If 2D Radial profile is selected, both the tool tip and cutter profile will be visualized during tool path replay. Cutter compensation instructions are automatically generated in the NC data output. An approach macro must be defined to allow the compensation to be applied.

● If 2D Radial tip is selected, the tool tip will be visualized during tool path replay. Cutter compensation instructions are automatically generated in the NC data output. An approach macro must be defined to allow the compensation to be applied.

● If None is selected, cutter compensation instructions are not generated in the NC data output. In this case, please refer to How to generate CUTCOM syntaxes.

Any user-defined PP words in macros are added to the cutter compensation instructions generated in the NC data output. Therefore you should be careful when specifying CUTCOM instructions in macros.

A negative Offset on contour (parameter in Geometry tab page) is possible for 2D radial profile output.

Pocketing High Speed Milling (HSM) Parameters

High Speed MillingSpecifies whether or not cornering for HSM is to be done on the trajectory. Corner radiusSpecifies the radius used for rounding the corners along the trajectory of a HSM operation.

Value must be smaller than the tool radius.

Limit angleSpecifies the minimum angle for rounding corners in the toolpath for a HSM operation.

Extra segment overlapSpecifies the overlap for the extra segments that are generated for cornering in a HSM operation. This is to ensure that there is no leftover material in the corners of the trajectory.

Cornering on side finish pathSpecifies whether or not tool path cornering is to be done on side finish path. Corner radius on side finish pathSpecifies the radius used for rounding the corners of the side finish path in a HSM operation. Value must be smaller than the tool radius. Limit angle on side finish pathSpecifies the minimum angle for rounding the corners of the side finish path in a HSM operation. Transition radiusSpecifies the radius at the start and end of the transition path when moving from one path to the next in a HSM operation.

Transition angleSpecifies the angle of the transition path that allows the tool to move smoothly from one path to the next in a HSM operation.

Transition lengthSpecifies a minimum length for the straight segment of the transition between paths in a HSM operation.

Pocketing Geometry

A Pocketing operation can be created for machining:

● Closed pockets: the tool machines the area delimited by hard boundaries

● Open pockets: the tool machines the area that has a least one soft boundary.

You can specify the following Geometry:

● Pocket Bottom (planar face or surface) with possible Offset on Bottom. Bottom may be Hard or Soft.

● Pocket Boundary (edges or sketch) with possible:

● Offset on Hard Boundary

● Offset on Soft Boundary

● Offset on Contour. If you specify an Offset on Contour, it is added to any defined Offset on Hard Boundary, Offset on Hard Boundary, and Offset on Island.

● Pocket Top plane with possible Offset on Top.

● Islands (defined by hard boundaries) with possible Offset on each island.

● Fixture or check elements with possible Offset on Check.

● Start and End points.

Specifying the Pocket Boundary

The pocket boundary must be closed. It can be specified in several ways:

● if the Contour Detection contextual command is set, select the pocket bottom. The boundary of the selected face will be proposed as pocket boundary.

● select edges. In this case the Edge Selection toolbar appears to help you specify the pocket boundary.

● select the By Belt of Faces or By Boundary of Faces contextual command. In this case the Face Selection toolbar appears to help you specify the pocket boundary.

● select the Sectioning contextual command. Please refer to Sectioning for details of how to use this capability.Please note that the sectioning selection method is not associative.

Specifying Start and End Points

You can select a Start point and an End point as preferential start and end positions for the operation. This allows better control for optimizing the program according to the previous and following operations.

http://bisel2dsy/jmndocr16/Doc/online/mfgug_C2/mfgugwd0206.htm#EdgeSelToolbar

http://bisel2dsy/jmndocr16/Doc/online/mfgug_C2/mfgugwd0206.htm#FaceSelToolbar


http://bisel2dsy/jmndocr16/Doc/online/cfyugspa_C2/cfyugspabt0200.htm

Note that the Start point can be located outside an open pocket. In this case, you must specify a clearance with respect to the pocket boundary.

Pocketing Tools

Recommended tools for pocketing are End Mills, Face Mills and T-Slotters.

Pocketing Feeds and Speeds

In the Feeds and Speeds tab page, you can specify feedrates for approach, retract, machining and finishing as well as a machining spindle speed.

Feedrates and spindle speed can be defined in linear or angular units.

A Spindle output checkbox is available for managing output of the SPINDL instruction in the generated NC data file. If the checkbox is selected, the instruction is generated. Otherwise, it is not generated.

Feeds and speeds of the operation can be updated automatically according to tooling data and the Rough or Finish quality of the operation. This is described in Update of Feeds and Speeds on Machining Operation.

Feedrate Reduction in Corners

You can reduce feedrates in corners encountered along the tool path depending on values given in the Feeds and Speeds tab page: reduction rate, maximum radius, minimum angle, and distances before and after the corner.

Feed reduction is applied to corners along the tool path whose radius is less than the Maximum radius value and whose arc angle is greater than the Minimum angle value.

For Pocketing, feedrate reduction applies to machining and finishing passes:

● for all corners in Back and forth mode

● for inside corners in Helical mode.

http://bisel2dsy/jmndocr16/Doc/online/mfgug_C2/mfgugrf0500.htm#FSUpdate

Feedrate reduction does not apply for macros or default linking and return motions.

Corners can be angled or rounded, and may include extra segments for HSM operations.

Slowdown Rate

You can use Slowdown rate in the Feeds and Speeds tab page to reduce the current feedrate by a given percentage.

The reduction is applied to the first channel cut and to the transitions between passes.

Combining Slowdown Rate and Feedrate Reduction in Corners

If a corner is included in a Slowdown path, the general rule is that the lowest percentage value is taken into account.

For example, if the Slowdown rate is set to 70 % and Feedrate reduction rate in corners is set to 50%, the feedrate sequence is: 100%, 70% (entry in slowdown), 50% (entry in corner), 70% (end of corner, still in slowdown), 100% (end of slowdown).

If Feedrate reduction rate in corners is then set to 75%, the feedrate sequence is: 100%, 70% (entry in slowdown), 70% (entry in corner: 75% ignored), 70% (end of corner, still in slowdown), 100% (end of slowdown).

Pocketing NC Macros

You can define transition paths in your machining operations by means of NC Macros. These transition paths are useful for providing approach, retract and linking motion in the tool path.

An Approach macro is used to approach the operation start point.

A Retract macro is used to retract from the operation end point.

A Return on Same Level macro is used in a multi-path operation to link two consecutive paths in a given level.

A Return between Levels macro is used in a multi-level machining operation to go to the next level.

A Return to Finish Pass macro is used in a machining operation to go to the finish pass.

A Clearance macro can be used in a machining operation to avoid a fixture, for example.

Specifying Ramping Approach Macros

When you edit a Ramping Approach macro in Pocketing, you can select the Parameter contextual command to access the parameters of the macro path.

If you select the Intermediate Levels checkbox, the approach macro is divided into 3 parts:

● a ramping approach from the top of the pocket to the intermediate level

● a horizontal path, which is the same as the first path if the machining mode is Back and Forth or the first closed path if the machining mode is Helical

● a ramping approach from the intermediate level to the machining level.

The yellow path in the figure below illustrates an intermediate level for a ramping approach macro in a Back and Forth Pocketing operation.

Pocketing P1/P2 Considerations

Note that P2 functionalities for Pocketing include Automatic Draft Angle, all Finishing parameters, and Sectioning for guiding element selection.To edit in P1 a Pocketing operation that was created in P2, the following parameter values must be set:

● Automatic draft angle = 0 deg

● Finishing mode = No finish path

● Side finish thickness = 0.0 mm

● Side finish thickness on bottom = 0.0 mm

● Bottom finish thickness = 0.0 mm

● Spring pass = no

● Avoid scallops on bottom = no

● HSM Cornering on side finish path = no

● HSM Corner radius = 1 mm

● HSM Limit angle = 10 deg.

● Zig Zag: the machining direction is reversed from one path to the next

● One way: the same machining direction is used from one path to the next.

Direction of cutSpecifies how machining is to be done. In Climb milling, the front of the advancing tool (in the machining direction) cuts into the material first.

In Conventional , the rear of the advancing tool (in the machining direction) cuts into the material first.

Machining toleranceSpecifies the maximum allowed distance between the theoretical and computed tool path. Fixture accuracySpecifies a tolerance applied to the fixture thickness. If the distance between the tool and fixture is less than fixture thickness minus fixture accuracy, the position is eliminated from the trajectory. If the distance is greater, the position is not eliminated. Type of contourIndicates whether the contouring type of corners is: Circular: the tool pivots around the corner point, following a contour whose radius is equal to the tool radius

Angular: the tool does not remain in contact with the corner point, following a contour comprised of two line segments

Optimized: the tool follows a contour derived from the corner that is continuous in tangent

Forced circular: This option may be used in certain complex cases when the Circular option does not give satisfactory results.

It creates tool paths comprising of portions of circular arcs (for example, when grooves are present along the trajectory and the tool is too big to penetrate).

Close tool pathSpecifies whether or not the program must close the tool path.

Tool position ON guideSpecifies the position of the tool tip on the guiding elements. Offset on contour and driving mode are already taken into account. Percentage overlapSpecifies the amount that the tool must go beyond the end point of a closed tool path according to a percentage of the tool diameter.

Compensation outputAllows you to manage the generation of cutter compensation (CUTCOM) instructions in the NC data output in Between Two Planes machining mode.


● If 2D Radial profile is selected, both the tool tip and cutter profile will be visualized during tool path replay. Cutter compensation instructions are automatically generated in the NC data output. An approach macro must be defined to allow the compensation to be applied.Please note that only Circular contouring type is supported with this output type.

● If None is selected, cutter compensation instructions are not automatically generated in the NC data output. However, CUTCOM instructions can be inserted manually. For more information, please refer to How to generate CUTCOM syntaxes.



CompensationSpecifies the tool corrector identifier to be used in the operation.

The corrector type (P1, P2, P3, for example), corrector identifier and corrector number are defined on the tool. When the NC data source is generated, the corrector number can be generated using specific parameters. Compensation application modeSpecifies how the corrector type specified on the tool (P1, P2, P3, for example) is used to define the position of the tool: Output point or Guiding point.

Profile Contouring Stepover ParametersSequencingSpecifies the order in which machining is to be done. Axial: axial machining is done first then radial

Radial: radial machining is done first then axial


Number of pathsDefines the number of tool paths in a radial strategy. Overhang for rework areasAllows a shift in the tool position with respect to the soft boundary of the rework area. Axial strategy modeDefines how the distance between two consecutive levels is to be computed:




Maximum depth of cutDefines the maximum depth of cut in an axial strategy. Number of levelsDefines the number of levels to be machined in an axial strategy. Automatic draft angleSpecifies the draft angle to be applied on the flanks between the top and bottom elements. BreakthroughSpecifies the distance in the tool axis direction that the tool must go completely through the part. Breakthrough is applied on the bottom element, which must be specified as soft. Only available in Between two planes mode.

Profile Contouring Finishing ParametersFinishing modeIndicates whether or not finish passes are to be generated on the sides and bottom of the area to machine.There are several possible combinations:

Side finishing can be done at each level or only at the last level of the operation.Bottom finishing can be done without any side finishing or with different combinations of side finishing.

Side finish thicknessSpecifies the thickness of material that will be machined by the side finish pass.

Side thickness on bottomSpecifies the thickness of material left on the side by the bottom finish pass.

Bottom finish path styleDefines the bottom finish path style: Zig zag or One way.

Spring passIndicates whether or not a spring pass is to be generated on the sides in the same condition as the previous Side finish pass. The spring pass is used to compensate the natural `spring' of the tool.

Profile Contouring High Speed Milling (HSM) Parameters

In a Profile Contouring, cornering for HSM is available for Roughing and Finishing passes in the following guiding modes:

● Between 2 planes

● Between curve and surfaces

● Between two curves.

Cornering applies to inside corners for machining or finishing passes. It does not apply to:

● outside corners (for example, produced by angular or optimized contouring mode).

● macros or default linking and return motions.

CorneringSpecifies whether or not cornering for HSM is to be done on the trajectory.

Corner radiusSpecifies the radius used for rounding the corners along the trajectory of a HSM operation. Value must be smaller than the tool radius.

Cornering on side finish pathSpecifies whether or not tool path cornering is to be done on the side finish path. Corner radius on side finish pathSpecifies the corner radius used for rounding the corners along the side finish path of a HSM operation. Value must be smaller than the tool radius.

Profile Contouring Geometry

A Profile Contouring operation can be created in one of the following Machining modes.

Between Two Planes

Tool follows contour between top and bottom planes while respecting user-defined geometry limitations and machining strategy parameters.


● Bottom (planar face or surface) with possible Offset on Bottom. Bottom may be Hard or Soft.

● Guide contour (edges or sketch) with possible Offset on Contour.

● Top plane with possible Offset on Top. Top may be Hard or Soft.

● Start and Stop Relimiting elements with possible Offsets.


Between Two Curves (P2 functionality)

Tool follows a trajectory defined by the Guide contour and Auxiliary Guide contour while respecting user-defined geometry limitations and machining strategy parameters.


● Guide contour and Auxiliary Guide contour (edges or sketch) with possible offsets:❍ a global radial Offset on Contour

❍ an Axial Offset 1 the Guide contour

❍ an Axial Offset 2 the Auxiliary Guide contour.



Guide contour is used for positioning the flank of the tool (radial positioning).

Auxiliary Guide contour is used for positioning the tool tip along the tool axis (axial positioning).

Cases when only the Guide contour is specified:

● If no Auxiliary Guide contour is specified, the Guide contour is used for positioning both the flank and the tip of the tool.

● If no Auxiliary Guide contour is specified, but an Auxiliary Guide contour offset (Axial Offset 2) is specified and it is different from the Guide contour offset (Axial Offset 1), the machining domain is defined between Guide contour Axial Offset 1 and Axial Offset 2 applied to the selected Guide contour.

● Only one contour geometry selection is necessary to define a multi-level tool path. This is useful when the Guide contour is selected and there is no suitable auxiliary guide curve on the geometry to machine. In this case, just specify the Number of levels in Stepover tab. See example below.

You can restrict machining to a specific zone by specifying Minimum depth and Maximum depth values. The depths are taken from the Guide contour. The Depth limitation check box must be activated in this case.

Between a Curve and Surfaces (P2 functionality)

Tool follows trajectory defined by a top guide curve and bottom surfaces while respecting user-defined geometry limitations and machining strategy parameters.


● Bottom (planar face or surface) with possible Offset on Bottom.If a negative offset value is specified, it must be less than the tool corner radius value.

● Guide contour (edges or sketch) with possible radial Offset on Contour and Axial Offset.An Axial Offset is only taken into account when more than one axial level is defined.



You can restrict machining to a specific zone by specifying Minimum depth and Maximum depth values. The depths are taken from the top guiding contour. The Depth limitation check box must be selected in this case.

By Flank Contouring (P2 functionality)

Tool flank machines vertical part surface while respecting user-defined geometry limitations and machining strategy parameters.


● Guiding flank (face parallel to tool axis) with possible Offset on Contour.

● Possible Offset on Bottom.



Specifying Guiding Contours

Guiding contours can be specified in several ways:

● if the Contour Detection contextual command is set in Between Two Planes mode, select the bottom element. The boundary of the selected face will be proposed as guiding contour.

● select edges. In this case the Edge Selection toolbar appears to help you specify the guiding contour.

● select the By Belt of Faces or By Boundary of Faces contextual command. In this case the Face Selection toolbar appears to help you specify the guiding contour.


Specifying Relimiting Elements

The guiding contour can be restricted by means of Start and Stop relimiting elements. The tool can be positioned In, On or Out with respect to a relimiting element. You can select a point or a curve as relimiting element.

A fast way to specify relimiting points is to right-click the guiding contour area in the sensitive icon of the dialog box and set the Relimitation point detection contextual command. When you select a guiding contour, its extremities will be used as relimiting elements.





Note that a relimiting point can be created anywhere along the guiding contour by means of the Add relimiting point contextual command. Just right-click the relimiting element area in the sensitive icon of the dialog box and select any position along the guiding contour.

Relimiting point selection can be made easier depending on the selected screen view. For example, you can select the Normal View icon in the View toolbar and a suitable face. The screen view is then perpendicular to the selected face and it is then easier to define relimiting point locations on the guide when moving the cursor.

Machining Discontinuous Guiding Curves

You can machine several discontinuous groups of guiding elements in all Profile Contouring modes (except By Flank Contouring).

These contours can be selected using the Edge Selection Toolbar. A Guide.x element is displayed for each selected continuous ordered contour.

The side to mill is shown by the orange arrow. Click on the arrow to inverse the side to mill.

The order of in which the geometric elements are selected determines the order in which they will be machined.


A linking macro can be used to link two discontinuous portions of the same tool path. Otherwise, a straight line is generated.

Once the selection of the guides is validated (that is, when the dialog box is displayed again), the following contextual menus become available.

On a guide in the graphic area:

On a guide in the dialog box icon:

Remove Element: Removes the selected element from the Guide.

You can also remove an element by picking it again, after having launched the Edge Selection toolbar. If the guide is no longer continuous, another guide is created.

Before After

You can add elements to a guide by simply picking the element, after having launched the Edge Selection toolbar. If the element picked is connected to that guide, it is automatically added to that guide. If the element picked is connected to two guides, the element is added and the two guides are merged into one.

Remove Guide x: Removes the selected guide.

Before After

Remove All Guides: Removes all guides

Before After

Connect Guide.x: Connects a guide to another one. Select the original guide, then the item Connect Guide.x in the contextual menu and the target guide.

Before After

The Connection Mode allows connection either by inserting a line or extrapolating a contour.

Connect All Guides: Connects all guides into one.

Before

After

Checking for Collisions between Tool and Guide Elements during Macro Motions and Machining Motions

Collision checking is done during macro motions and machining motions (for corner and angle contouring). All guiding elements defined on the operation are taken into account during this verification. However, in some cases, it can be useful to deactivate collision checking with the guides (see example below).

In the following figure, collision avoidance during the circular approach macro is not necessary.

In the following figure, there is no collision avoidance during the circular approach.

The Collision Avoidance capability allows you to manage this collision checking.

When you select Collision checking on the Geometry tab page, the following dialog box appears.

When the Include guiding elements check box is selected, guides are checked for collisions during macro motions and machining motions. By default, the check box is selected.

When the check box is not selected, no collision verification is done with the guides for macro motions and for machining motions during tool plunges.

In the specific case when there is no selected top element and no offset defined on the bottom element, there is no tool motion to avoid the guiding elements, so no collisions will be detected (for macro motions only).

Profile Contouring Tools

Recommended tools for Profile Contouring are End Mills, Face Mills, Conical Mills and T-Slotters.

Drills, Spot Drills, Center Drills, and Countersinks can also be used.

A Spindle output check box is available for managing output of the SPINDL instruction in the generated NC data file. If the check box is selected, the instruction is generated. Otherwise, it is not generated.




Feed reduction is applied to corners along the tool path whose radius is less than the Maximum radius value and whose arc angle is greater than the Minimum angle value. Corners can be angled or rounded.

For Profile Contouring, feedrate reduction applies to inside corners for machining or finishing passes. It does not apply for macros or default linking and return motions.

If a cornering is defined with a radius of 5mm and the Feedrate reduction in corners set to a lower radius value, the feedrate will not be reduced.

Profile Contouring NC Macros





A Linking macro may be used in several cases, for example:

● to link two non consecutive paths

● to access finish and spring passes.





Profile Contouring P1/P2 Considerations

Note that P2 functionalities for Profile Contouring include Automatic Draft Angle, all Finishing parameters, and Sectioning for guiding element selection. To edit in P1 a Profile Contouring operation that was created in P2, the following parameter values must be set:

● Automatic draft angle = 0 deg

● Finishing Mode = No finish path


● Side finish thickness on bottom = 0.0 mm


● Spring pass = no.

The information in this section will help you create and edit Prismatic Roughing operations in your manufacturing program.

Select the Prismatic Roughing icon then the geometric components to be machined.


● Machining criteria

● Radial stepover conditions

● Axial stepover conditions


Specify the tool to be used and speeds and feeds .

You can also define transition paths in your machining operations by means of NC macros as needed.

Prismatic Roughing: Machining Strategy

Prismatic Roughing: Machining parameters

Tool path style Indicates the cutting mode of the operation.

● Helical: the tool moves in successive concentric passes from the boundary of the area to machine towards the interior. The tool moves from one pass to the next by stepping over.


Machining tolerance Maximum allowed distance between the theoretical and computed tool path. Consider the value to be the acceptable chord error.

Cutting mode Specifies the position of the tool regarding the surface to be machined. It can be:

Climb or Conventional.

Machining mode Defines the type of area to be machined:

● By plane: the whole part is machined plane by plane

● By area: the whole part is machined area by area

then

● Pockets only: only pockets on the part are machined

● Outer part: only the outside of the part is machined

● Outer part and pockets: the whole part is machined outer area by outer area and then pocket by pocket.

Helical movement

This parameter is available when the tool path style is set to Helical. It specifies the way the tool moves in a pocket or an external zone. It can be:

● Inward: the tool starts from a point inside the zone and follows inward paths parallel to the boundary.

● Outward: the tool starts from a point inside the zone and follows outward paths parallel to the boundary.

● Both: For pockets, the tool starts from a point inside the pocket and follows outward paths parallel to the boundary. For external zones, the tool starts from a point on the rough stock boundary and follows inward paths parallel to the boundary.

Always stay on bottom This parameter is available when the tool path style is set to Helical. When this parameter is set, the linking path

between two areas remains in the plane currently machined.

Part contouring With part contouring switched on, the tool machines the outside contour of the part before roughing.

Contouring pass ratio This parameter is available when the tool path style is set to Back and Forth. It adjusts the position of the final pass for removing scallops. This is done by entering a percentage of the tool diameter (0 to 50).

Truncated transition paths This parameter is available when the tool path style is set to Back and Forth. It enables the tool to follow the external profile more exactly by allowing the transition portion of the trajectory to be truncated.

Not truncated: Truncated:

Prismatic Roughing: Radial parameters

Stepover, which can be defined by one of the following.

● Overlap ratio: the overlap between two passes, given as a percentage of the tool diameter

● Overlap length: the overlap between two passes, given as a distance

● Stepover ratio: the stepover between two passes, given as a percentage of the tool diameter

● Stepover length: the stepover between two passes, given as the maximum distance between passes.

Prismatic Roughing: Axial parameters

Maximum cut depth Depth of the cut effected by the tool at each pass.

Prismatic Roughing: High Speed Milling parameters

The following parameters are available when the High speed milling checkbox is selected in the HSM tab page.

Corner radiusSpecifies the radius used for rounding the corners along the trajectory of a HSM operation. The tool path is rounded to give a smoother path that can be machined faster. The minimum value of the corner radius is the radius of the tool.

Corner radius on part contouring Specifies the radius used for rounding the corners along the Part contouring pass of a HSM operation. This radius must be smaller than the value set for the Corner radius parameter.

Prismatic Roughing: Geometry

You can specify the following geometry:

Part with possible offset.

Rough stock is required.

Check element with possible offset. The check element is often a clamp that holds the part and therefore is not an area to be machined.

Safety plane. The safety plane is the plane that the tool will rise to at the end of the tool path in order to avoid collisions with the part. You can also define a new safety plane with the Offset option in the safety plane contextual menu. The new plane will be offset from the original by the distance that you enter in the dialog box.

Top plane which defines the highest plane that will be machined on the part,

Bottom plane which defines the lowest plane that will be machined on the part,

Imposed plane that the tool must pass through. Use this option if the part that you are going to machine has a particular shape (a groove or a step) that you want to be sure will be cut.

Note that if you wish to use all of the planar surfaces in a part as imposed planes, use the Search/View contextual command to select them. When searching for planar surfaces, you can choose to find either:

● all of the planar surfaces in the part

● or only the planes that can be reached by the tool you are using.

To use planar surfaces as imposed planes:

● Select the planar surfaces

● Select Offset in the contextual menu and enter a value equal to the machining tolerance plus the offset value on part:

❍ If the machining tolerance is 0.1 mm and there is no offset on part, enter 0.1 mm as offset for the imposed plane.

❍ If the machining tolerance is 0.1 mm and the offset on part is 1 mm, enter 1.1 mm as offset for the imposed plane.

This ensures that the imposed planar surface is respected to within the offset and tolerance values.

Start point where the tool will start cutting. There are specific conditions for start points:

● They must be outside the machining limit. Examples of machining limits are the rough stock contour, a limit line, an offset on the rough stock, an offset on the limit line, etc.

● They must be positioned so as to avoid collisions with either the part or the check element. If a start point for a given zone causes a collision, the tool will automatically adopt ramping approach mode.

● The distance between the start point and the machining limit must be greater than the tool radius plus the machining tolerance. If the distance between the start point and the machining limit is greater than the tool radius plus the safety distance, the start point will only serve to define the engagement direction.

● If there are several start points for a given area, the one that is used is the first valid one (in the order in which they were selected) for that area. If there are several possible valid points, the nearest one is taken into account.

● One start point may be valid and for more than one area.

● If a limit line is used, the tool will approach outer areas of the part and pockets in ramping mode towards the outside of the contour. The tool moves from the outside towards the inside of this type of area. In this case, you must define the start point.

Note that if you use a limit line or if you use an inner offset on the rough stock, the start point may be defined inside the initial rough stock. The rules concerning the domain of the contour line or the offset on the rough stock contour line above must be applied.

Whenever possible, the end of the engagement associated to the start point corresponds to the beginning of the sweeping path. If this is not possible, the path will be cut to respect the constraint imposed by the start point.

Inner points (only active if the Drilling mode has been selected in the Macro tab). There are specific conditions for inner points:

● They are usable for pockets only.

● They must be positioned so as to avoid collisions with either the part or the check element. If an inner point for a given pocket causes a collision, the tool will adopt a new inner point generated automatically.

● The inner point must lie inside the pocket or inside the portion of the pocket that is machined.

● If there are several inner points for a given pocket, the one that is used is the first valid one (in the order in which they were selected) for that pocket.

● A point cannot be valid for several pockets.

Limiting contour which defines the machining limit on the part, with the Side to machine parameter.

Automatic horizontal areas detection

When this option is inactive, the only way to ensure that a cutting plane corresponds with an horizontal area is to define an Imposed plane crossing the area. This means that you have to consider the offset on part. This plane applies to the whole part (which is not necessary). If there are several horizontal areas to consider at different levels you have to define all of the corresponding imposed planes.

Select this option to:

● detect automatically horizontal areas on the part

● limit the cutting plane effect to these areas

● apply a dedicated offset on the part for these areas.

Then enter the value of the offset to apply on the areas (Offset on areas) and define the Maximum angle that can be considered as horizontal. The angle is measured perpendicular to the tool path.

If the machining mode is By area, the tool path will look like this:

If the machining mode is By plane, the tool path will look like this:

The cutting planes in green are the Standard roughing tool paths, the red ones are those computed for the horizontal areas detected.

The computation of horizontal areas is not possible if the part is made of a cloud of points (STL). This option is not compatible with the use of offset groups.

Horizontal areas are always defined as pockets (no distinction outer part/pocket). You should use a limiting contour to mill Pocket only or Outer part areas.

Offset Defines the distance that the tool can overshoot the Position. It is expressed as a percentage of the tool diameter. This parameter is useful in cases where there is an island near the edge of the part and the tool diameter is too wide to allow the area behind the island to be machined. This parameter can only be used if the Position is inside or outside.

Limit Definition Defines what area of the part will be machined with respect to the limiting contour(s). It can either be inside or outside. In the pictures below, there are three limiting contours on the rough stock. The yellow areas will be machined.

Side to machine: Inside Side to machine: Outside

Note that if you are using a limiting contour, you should define the start point so as to avoid tool-material collision.

Prismatic Roughing: Tools

The only supported tools are End Mills.

Prismatic Roughing: Feeds and Speeds







Feed reduction is applied to corners along the tool path whose radius is less than the Maximum radius value and whose arc angle is greater than the Minimum angle value.

When machining pockets, feedrate reduction applies to inside and outside corners for machining or finishing passes. It does not apply for macros or default linking and return motions.

Corners can be angled or rounded, and may include extra segments for HSM operations.


Slowdown Rate

You can use Slowdown rate in the Feeds and Speeds tab page to reduce the current feedrate by a given percentage.

In Helical tool paths, the reduction is applied to the first channel cut.

In Back and Forth tool paths, the reduction is applied to the first channel cut and to the transitions between passes.

Combining Slowdown Rate and Feedrate Reduction in Corners

If a corner is included in a Slowdown path, the general rule is that the lowest percentage value is taken into account.

For example, if the Slowdown rate is set to 70 % and Feedrate reduction rate in corners is set to 50%, the feedrate sequence is: 100%, 70% (entry in slowdown), 50% (entry in corner), 70% (end of corner, still in slowdown), 100% (end of slowdown).

If Feedrate reduction rate in corners is then set to 75%, the feedrate sequence is: 100%, 70% (entry in slowdown), 70% (entry in corner: 75% ignored), 70% (end of corner, still in slowdown), 100% (end of slowdown).

Prismatic Roughing: Macro Data

The following types of macro can be defined on a Prismatic Roughing operation:

● Automatic roughing

● Pre-motion

● Post-motion.

For more information on how to save or load an existing macro, please refer to Build and use a macros catalog.

Automatic Roughing Macros

You must select one of the following approach modes to specify how the tool will engage the material:

● Plunge: the tool plunges vertically.

● Drilling: the tool plunges into previously drilled holes. You can change the Drilling tool diameter, Drilling tool angle and Drilling tool length.

● Ramping: the tool moves progressively down at the Ramping angle. Ramping approach mode applies to pockets but also outer areas in given conditions:

❍ If a limit line is used, the tool will approach outer areas of the part and pockets in ramping mode.

❍ If a lateral approach is not possible (due to the check element), the approach is made in ramping mode.

● Helix: the tool moves progressively down at the ramping angle with its center along a (vertical) circular helix of Helix diameter.

Approach distanceEngagement distance for the selected approach mode.

Axial safety distanceMaximum distance that the tool will rise to when moving from the end of one pass to the beginning of the next.

Radial safety distance Distance that the tool moves horizontally before it begins its approach.

Optimize retract Selecting this checkbox optimizes tool retract movements. This means that when the tool moves over a surface where there are no obstructions, it will not rise as high as the safety plane because there is no danger of tool-part collisions. The result is a gain in time.

Note that in some cases (where areas of the part are higher than the zone you are machining and when you are using a safety plane), the tool may cut into the part. In this case, deselect the Optimize retract checkbox.

Pre-Motion Macros

These are macros that are built by the user using the elementary motions proposed in the Current Macro


Toolbox. A pre-motion macro is applied between the rapid motion from safety plane and the automatic macro.

Post-Motion Macros

These are macros that are built by the user using the elementary motions proposed in the Current Macro Toolbox. The post-motion macro between the automatic macro and the rapid motion from safety plane.

Groove Milling OperationsThe information in this section will help you create and edit 2.5 axis Groove Milling operations in your manufacturing program.

Select the Groove Milling icon then select the geometry to be machined .




● axial and radial stepover conditions

● finishing.

The Machining direction (Top/Bottom, Bottom/Top) and Axial strategy (Standard, Middle, Middle alternate) parameters determine the tool path ordering for machining the groove as follows:

● The roughing pass ordering respects the Machining direction definition

● If Side finish pass is defined: a side finish pass is done for each roughing level

● If Top and/or Bottom finish passes are defined, Top and/or Bottom finish pass are done in order to minimize tool motion between levels. For example, in Top/Bottom machining with Top and Bottom finish passes, top finishing is done just after the first machining level and just before the second machining level.

In Bottom/top machining with Top and Bottom finish passes, bottom finishing is done just after the first machining level and just before the second machining level.

● The tool compensation point is taken into account for each pass. This point is switched automatically during a Return between levels macro whenever the next level to machine requires a different compensation point.

Groove Milling Strategy Parameters

Groove Milling: Machining ParametersTool path styleIndicates the cutting mode of the operation:



Direction of cutSpecifies how machining is to be done.

● In Climb milling, the front of the advancing tool (in the machining direction) cuts into the material first.

● In Conventional , the rear of the advancing tool (in the machining direction) cuts into the material first.

Machining toleranceSpecifies the maximum allowed distance between the theoretical and computed tool path. Fixture accuracySpecifies a tolerance applied to the fixture thickness. If the distance between the tool and fixture is less than fixture thickness minus fixture accuracy, the position is eliminated from the trajectory. If the distance is greater, the position is not eliminated. Close tool pathSpecifies whether or not the program must close the tool path.

Groove Milling: Axial/Radial Stepover Parameters

Machining directionDefines how the distance between two consecutive levels is to be computed:

● Top/Bottom

● Bottom/Top.

Axial strategyDefines how the tool path is to be ordered for machining the groove:

● Standard

Maximum depth of cutDefines the maximum depth of cut in an axial strategy. Number of levelsDefines the number of levels to be machined in an axial strategy. BreakthroughSpecifies the distance in the tool axis direction that the tool must go completely through the part. Breakthrough is applied on the bottom element, which must be specified as soft.


Number of pathsDefines the number of tool paths in a radial strategy.

Groove Milling Finishing Parameters

Finishing modeIndicates whether or not finish passes are to be generated on the sides, top and bottom of the area to machine. There are several possible combinations:

For example, Top/Bottom machining with side, top and bottom finish passes:

Side finish thicknessSpecifies the thickness of material that will be machined when finishing the flank of the groove.

Bottom finish thicknessSpecifies the thickness of material that will be machined when finishing the bottom of the groove.

Bottom thickness on side finishSpecifies the bottom thickness used for last side finish pass, if side finishing is requested on the operation.

Top finish thicknessSpecifies the thickness of material that will be machined when finishing the top of the groove.Top/bottom finish path styleDefines the finish path style for the top and bottom finish passes: Zig zag or One way. Spring passIndicates whether or not a spring pass is to be generated on the sides in the same condition as the previous Side finish pass. The spring pass is used to compensate the natural spring of the tool.

Groove Milling Geometry

Tool follows a guiding contour between top and bottom of the groove while respecting user-defined geometry limitations and machining strategy parameters.


● Bottom (planar face or surface) with possible Offset on Bottom. Bottom may be Hard or Soft.

● Top plane with possible Offset on Top. Top may be Hard or Soft.

● Open or closed guiding contour (edges or sketch) with possible Offset on Contour.



Specifying Guiding Contours

Guiding contours can be specified in several ways:

● if the Contour Detection contextual command is set, select the bottom element. The boundary of the selected face will be proposed as guiding contour.


● select the By Belt of Faces or By Boundary of Faces contextual command. In this case the Face



Selection toolbar appears to help you specify the guiding contour.


Specifying Relimiting Elements

The guiding contour can be restricted by means of Start and Stop relimiting elements. The tool can be positioned In, On or Out with respect to a relimiting element. You can select a point or a curve as relimiting element.

A fast way to specify relimiting points is to right-click the guiding contour area in the sensitive icon of the dialog box and set the Relimitation point detection contextual command. When you select a guiding contour, its extremities will be used as relimiting elements.

Note that a relimiting point can be created anywhere along the guiding contour by means of the Add relimiting point contextual command. Just right-click the relimiting element area in the sensitive icon of the dialog box and select any position along the guiding contour.

Checking for Collisions between Tool and Guide Elements during Macro Motions

Collision checking is done during macro motion. All guiding elements defined on the operation are taken into account during this verification. However, in some cases, it can be useful to deactivate collision checking with the guides (see example below).

The Collision Avoidance capability allows you to manage this collision checking.

When you select Collision checking on the Geometry tab page, the following dialog box appears.

When the Include guiding elements checkbox is selected, guides are checked for collisions during macro motion. By default the checkbox is selected.

When the checkbox is not selected, no collision verification is done with the guides during macro motions.

By default the checkbox is selected.

Groove Milling Tools



A Groove Milling operation uses a T-Slotter.

Groove Milling Feeds and Speeds







Feed reduction is applied to corners along the tool path whose radius is less than the Maximum radius value and whose arc angle is greater than the Minimum angle value. Corners can be angled or rounded.

For Groove Milling, feedrate reduction applies to inside corners for machining or finishing passes. It does not apply for macros or default linking and return motions.

If a cornering is defined with a radius of 5mm and the Feedrate reduction in corners set to a lower radius value, the feedrate will not be reduced.

Groove Milling NC Macros





A Linking macro may be used in several cases, for example:

● to link two non consecutive paths

● to access finish and spring passes.





Groove Milling P1/P2 Considerations

Note that P2 functionalities for Groove Milling include all Finishing parameters, and Sectioning for guiding element selection.To edit in P1 a Groove Milling operation that was created in P2, the following parameter values must be set:



● Top finish thickness = 0.0 mm


● Spring pass = no.

Point to Point OperationsThe information in this section will help you create and edit Point to Point operations in your manufacturing program.

Select the Point to Point icon then set the strategy parameters for defining:

● a sequence of elementary Goto Point, Goto Position and Go Delta tool motions

● machining conditions.

Specify the tool to be used, NC macros , and feeds and speeds as needed.

Point to Point Strategy Parameters

Point to Point Tool MotionsGoto PointA tool motion defined by the point the tool tip has to reach.

Geometry can be selected as follows:

● Direct selection on the part (points, vertices, and so on)

● Direct indication in a pre-selected surface. Only selection done within the topological limits of the surface are taken into account.

● Indication of points to be projected onto a user-defined indication plane.This indication plane is considered as infinite (it has no topological limits). This allows point indication outside the part boundaries. It is a temporary element used as an aid for selection. It is not saved after operation edition.

Goto PositionA tool motion defined by positioning the tool in contact with a part element, a drive element and possibly a check element, while taking To / On / Past conditions into account. Go DeltaA tool motion defined by a displacement relative to a previous Point, Position or GoDelta motion location. Types of Go Delta motion are as follows.

● Components: relative motion defined by DX, DY, DZ displacements from previous motion location.

● Along Y axis: relative motion along Y axis (current axis system) on a user specified Distance, from previous motion location.

● Along X axis: relative motion along X axis (current axis system) on a user specified Distance, from previous motion location.

● Parallel to Line: relative motion on a user specified Distance, parallel to a user selected Line, from previous motion location.

● Normal to Line: relative motion on a user specified Distance, normal to a user selected Line, from previous motion location. The tool motion is done in a plane perpendicular to the tool axis.

● Angle to Line: relative motion on a user specified Distance, along a line computed from user defined Angle and Line. The tool motion is done in a plane perpendicular to the tool axis.

Point to Point Machining ParametersMachining toleranceSpecifies the maximum allowed distance between the theoretical and computed tool path.

Offset along tool axisDefines an offset along the tool axis for all positions of the tool path (it is taken into account for all the positions of the operation).

First compensationSpecifies the tool corrector identifier to be used in the operation.


Point to Point Tool

All Milling and Drilling tools can be used in this type of operation.

Point to Point Feeds and Speeds

In the Feeds and Speeds tab page, you can specify feedrates for approach, retract and machining as well as a machining spindle speed.




In Point to Point operations, a local feedrate can be defined for all tool motions (except the first motion, which must be either RAPID or a specific feedrate). The local feedrate is applied instead of the machining feedrate during the tool motion to reach the tool position. For the operation start point, machining feedrate is taken into account.

Point to Point NC Macros

You can define transition paths in your machining operations by means of NC Macros. These transition paths are built from elementary motions and are useful for providing approach and retract motion in the tool path.

● An Approach macro is used to approach the operation start point.

● A Retract macro is used to retract from the operation end point.

You can use the following icons to define the elementary motions of macros in a Point to Point operation:

| | | |

| | | |

| | | -> distance along a given direction

| | -> axial motion to a plane

| -> PP word

-> axial motion

The general procedure is described in Define Macros on a Milling Operation.

Axial Machining Strategy Parameters

Strategy parameters are managed in the Strategy tab page .

General Parameters

Approach clearance (A)Defines a safety distance along the tool axis for approaching the hole reference.The manufacturing attribute is MFG_CLEAR_TIP. Approach clearance 2 (A2)Only for Boring and Chamfering, Chamfering Two Sides, and Back Boring operations, this parameter defines a safety distance along the tool axis for approaching the chamfering or back boring pass. The manufacturing attribute is MFG_CLEAR_TIP_2. Breakthrough (B)Defines the distance in the tool axis direction that the tool goes completely through the part.The manufacturing attribute is MFG_BREAKTHROUGH.

Plunge modeAllows you to specify an axial plunge from the hole reference at plunge feedrate prior to machining.

The overall plunge distance is determined as follows: Approach clearance + (Plunge depth - Plunge offset)where Plunge depth is determined by a tool tip or tool diameter value.

The manufacturing attribute is MFG_PLUNGE_MODE. Plunge offset (Po)Specifies the plunge offset value.The manufacturing attribute is MFG_PLUNGE_OFFST. Plunge diameter (Pd)Specifies the plunge diameter value.The manufacturing attribute is MFG_PLUNGE_DIAMETER. Plunge tip (Pt)Specifies the plunge tip distance.The manufacturing attribute is MFG_PLUNGE_TIP. Plunge for chamfering For a Boring and Chamfering operation, if a Plunge mode is selected (By Tip or By Diameter), you can deactivate the plunge motion for the Chamfering phase of the operation by deselecting the Plunge for chamfering checkbox. In this case, the plunge motion will be done for the boring phase only.Depth modeDefines how the depth computation is to be done.Depending on the type of operation this can be done as a function of the tool tip, shoulder, diameter or a distance value. The manufacturing attribute is MFG_DEPTH_MODE. Dwell modeDefines the dwell by means of a number of revolutions or time duration.

● Revolutions: Specifies the number of revolutions for the dwell

● Time: Specifies the time duration of the dwell.

Shift modeSpecifies the shift mode used to offset the tool just before retracting.

● By linear coordinatesShift along X: Specifies the shift along X Shift along Y: Specifies the shift along Y Shift along Z: Specifies the shift along Z

● By polar coordinatesShift distance: Specifies the shift distance Shift angle: Specifies the shift angle

● None.

The values entered for the selected shift mode determine the angle at which the active part of the boring bar stops and the amount of the tool displacement.

For a shift defined by polar coordinates (90deg, 1.5mm), the tool is displaced 1.5mm as indicated by the arrow in the figure

below.

The same shift motion could be obtained by the linear coordinates (0mm, 1.5mm, 0mm).Max depth of cut (Dc)Defines the maximum depth of cut for:

● each peck in a Drilling Deephole operation

● each break chips pass in a Drilling Break Chips operation.

The manufacturing attribute is MFG_AXIAL_DEPTH. RetractDefines the retract clearance after the machining pass in a Back Boring operation.

The manufacturing attribute is MFG_RETRACT_CLEAR_TIP. Retract offset (Or)Defines the value of:

● the back motion used to break chips after each drilling pass in a Drilling Break Chips operation

● the offset where machining feedrate starts before each new peck in a Drilling Deephole operation.

The manufacturing attribute is MFG_OFFSET_RET.

Decrement rateIn a Drilling Deephole operation, this parameter decreases the effective depth of cut at each new peck until the total depth is reached.

Depth of peck 1 = Max depth of cut (Dc)Depth of peck 2 = Dc * (1-Decrement rate)Depth of peck 3 = Dc * (1-2*Decrement rate)and so on.

If Decrement rate is equal to zero, the Maximum depth of cut is applied at each new peck as a constant step.The manufacturing attribute is MFG_DEPTH_DEC.

Decrement limitCoefficient used to determine the maximum allowed depth of cut for a peck in a Drilling Deephole operation.

The depth of a new peck never becomes smaller than the Maximum depth of cut multiplied by the Decrement limit.

That is:Depth of current peck > Maximum depth of cut * Decrement limit.

When:Depth of current peck = Maximum depth of cut * Decrement limitthis depth is kept for all remaining pecks until the total depth is reached.

The value of Decrement limit must be greater than zero.The manufacturing attribute is MFG_DEPTH_LIM.

Example of Decrement rate and Decrement limit

A Drilling Deephole operation uses the following parameters:Maximum depth of cut = 10mmDecrement rate = 0.1Decrement limit = 0.8

Therefore, depth of current peck will always be greater than 8mm (that is, 10mm*0.8).

Depth of peck 1 = 10mmDepth of peck 2 = 9mmDepth of peck 3 = 8mmDepth of remaining pecks = 8mm. Automatic ROTABLAllows the generation of rotation motions between drilling points that have different tool axes.

This capability works with a 3-axis milling machine with rotary table when ROTABL/ output is requested.Rotary motions are displayed during Replay.ROTABL/ instructions are generated in the output file.Facilitates environment setup by minimizing the requirement on post processors (avoids having to deal with X, Y, Z, I, J, K outputs for rotary tables).Provides the NC programmer with a more accurate tool path simulation for machine tools with rotary table.

Note: No rotary motion is performed if a linking macro motion is defined (and activated) on the drilling operation. If activated, the linking macro is always performed between the points to machine.

Output CYCLE syntax Specifies how the NC output is to be generated: output in CYCLE mode or in GOTO mode.

If you want to generate CYCLE statements, you must select the Output CYCLE syntax checkbox in the Strategy tab page and set the Syntax Used option to Yes in the NC Output generation dialog box.Otherwise, GOTO statements will be generated.

Note that when several axis orientations are present in a machining pattern, output of the components of the tool axis orientation is possible whenever the NC data format is set to Axis (X, Y, Z, I, J, K) in the Part Operation's Machine Editor. First compensationSpecifies the first tool compensation number for the operation. Second compensationFor Boring and Chamfering and Chamfering Two Sides operations, this parameter pecifies the second tool compensation number for the operation.

Circular Milling and Thread Milling Parameter

Machining toleranceSpecifies the maximum allowed distance between the theoretical and computed tool path.

Specific Circular Milling Parameters

Machining modeSpecifies the machining mode: Standard or Helical. Distance between paths (Dp)Defines the maximum distance between two consecutive tool paths in a radial strategy.

Helix modeDefines how the helix computation is to be done.The manufacturing attribute is MFG_HELIX_MODE.

Pitch (P): Specifies the helix pitchAngle (Ang): Specifies the helix angle.

Output styleAllows you to manage the generation of Cutter compensation (CUTCOM) instructions in the NC data output:





Axial Machining Geometry Considerations

Geometry parameters are managed in the Geometry tab page .

Machining Patterns

A machining pattern comprises two sets of data:

● Patten geometry: hole positions/axes, top element

● Pattern usage or technology data: Ordering mode, Jump distance, local entry/exit distances, local depth, activate/deactivate status.

When you create a new axial machining operation, the New Pattern command in the combo prompts you to create a machining pattern for the operation.

You can add positions to this new machining pattern by clicking the sensitive text (No Point or x Points). This opens the Pattern Selection dialog box that lists all available machining and design patterns. Just select one of the existing patterns and/or select geometry in the 3D view to define the hole positions.

The new machining pattern is created when you create the machining operation. The pattern geometry and technology data is stored and the new pattern is assigned an identifier Machining Pattern.x.

If there are already machining patterns on previous operations, the combo allows a quick selection of an existing pattern. If selected, the existing pattern is shared between the operations.

You can also use the following commands in the combo for assigning a machining pattern to the operation.

Copy from Current: The machining pattern (geometry and technology data) is duplicated. The pattern cannot be shared. It is possible to modify the machining data in the current machining operation without impacting other operations.

New from Current (share geometry): The machining pattern (geometry and technology data) is duplicated. The pattern can be shared. If the pattern is modified, all operations using it will be impacted.

New Pattern: A new machining pattern is created with the geometry and technology data that you specify.

Modification of a machining pattern is possible using the Machining Pattern editor only. This editor can be opened by double-clicking the machining pattern in the manufacturing view. Please refer to Machining Patterns for more information.

Note that it is possible to reference in a machining pattern one or more 3D Wireframe features (that is, Projection, Symmetry, Rotation and Translation operators) containing at least one point.


Pattern Ordering Modes

Holes that are selected for a machining pattern can be ordered according to the following modes:

● Closest: to obtain the shortest possible tool path

● Manual: to obtain a user-defined numbered sequence

● By Band: to obtain a Zig Zag or One Way configuration according to a set of bands that have a user-defined width.❍ Zig Zag ordering of a pattern of 40 points for a band width of 18mm is illustrated below:

❍ One Way ordering of the same points and same band width is illustrated below:

● Reverse Ordering: Reverses the numbered sequence of pattern points (for example, points numbered 1 thru 10 will become numbered 10 thru 1).

Managing Pattern Points

Contextual Menu on 'No Points / x Points' Sensitive Text

A number of contextual commands are available for managing hole positions when you right click the 'No Points / x Points' sensitive text in the Geometry tab page.

● Remove All Positions: Removes all positions from the pattern.

● Remove: Displays a dialog box for removing selected positions from the pattern.

● Deactivate: Displays a dialog box for deactivating selected points of the pattern.

● Move After: Displays a dialog box for moving one or more positions after a specified position in the pattern. Only available when Pattern Ordering mode is set to Manual.

● Analyze: Displays the Geometry Analyser for consulting the status of the referenced geometry.

● Find Features Through Faces: Allows you to quickly locate circular edges in a selected face. Please refer to Select Hole Design Features for Machining.

Contextual Menu on Pattern Points

A number of contextual commands are available when you right-click a pattern point.

● Deactivate the Point: Deactivates the selected point in the pattern. An O symbol indicates that the point is omitted from the pattern. A deactivated point can be activated in the pattern again.

● Invert Selection: All omitted points are retained in the pattern again; pattern points become omitted points.

● Select All: Allows you to include all omitted points in the pattern again.

● Set as Start Point: Allows you to choose the start point for the pattern.

● Renumber: Allows you to renumber points in the pattern. Only available when Pattern Ordering mode is set to Manual.

● Edit Entry Distance and Edit Exit Distance:Allows you to locally edit Entry and Exit distances at individual points in a hole pattern. This can be useful for locally specifying a clearance that is greater than the one defined by the jump distance/approach clearance discussed below.

● Edit Depth: Allows you to edit the depth of a pattern point.

● Restore Associativity: Restores the original values taken from the selected design feature if these were modified by the user, and so restore associativity with the feature.

● Edit Local Axis: Allows you to locally modify the tool axis at a point. The Tool Axis dialog box appears.

Choose one of the proposed methods for defining tool axis orientation:

Manual. Choose one of the following:

❍ Components to define the tool axis orientation by means of I, J and K components.

❍ Angles to define the orientation by means of a rotation specified by means of one or two angles.

Selection. If you select a line or linear edge, the tool axis will have the same orientation as that element. If you select a planar element, the tool axis will be normal to that element.

Points in the View. Just select two points to define the orientation.

Feature defined. Select a machining feature in the 3D viewer. For example, if you select an axial machining feature then the axis of the feature is taken as the tool axis.

The tool axis is visualized by means of an arrow. The direction can be reversed by clicking Reverse Direction in the dialog box. Just click OK to accept the specified tool axis orientation.

You can also choose to display the tool at the Default position or at a User-defined position.

For a user-defined position, click the [...] button and select the desired position in the 3D viewer.

For more information about this dialog box please refer to Define the Tool Axis.

● Insert after Current Position: Allows you to insert one or more positions (or patterns) after the current point in the pattern. Only available when Pattern Ordering mode is set to Manual.

● Remove Current Position: Deletes the current point from the pattern.

● Remove Linked Positions: Deletes the current point and all linked positions from the pattern. Linked positions are points from the same design pattern, for example.


Inversing Pattern Ordering

A Inverse pattern ordering option is available in the Geometry tab page to allow an operation to locally override the ordering of the Machining Pattern by inversing it.

● If not selected, the Machining Pattern will be machined as defined (and as shown in the 3D view).

● If selected, the tool path computation will begin at the last point and finish at the first point.This will not modify the ordering on the Machining Pattern: the pattern numbers shown in the 3D View are not modified.

This option is useful in the following cases.

● When machining symmetrical parts. Please refer to Opposite hand machining.

● To save machining time when managing two operations sharing the same Machining Pattern on a large part. The first operation can be set to machine from the first position to the last one, and the second operation can be set machine from the last position to the first one.

Overall Tool Axis Orientation

Right click the Tool axis strategy sensitive text in the Geometry tab page and select one of the following options to specify the general tool axis orientation:

● Fixed Axis: the tool axis orientation is the same for all the selected points

● Variable Axis: the tool axis orientation can vary from one point to another

● Normal to PS Axis: the tool axis orientation is determined by the normal to the selected part surface.

Note that the tool axis orientation can be inverted by clicking the tool axis symbol in the Geometry tab page.

Projection and Top Element Modes

In the Geometry tab page you can choose between Projection and Top Element modes by clicking on the sensitive text.

The following figure illustrates Projection mode. The reference pattern points are projected onto the selected part surface. The projected points and the axes normal to the surface define the hole positions to be drilled.

http://bisel2dsy/jmndocr16/Doc/online/mfgug_C2/mfgugmt0600.htm

The following figure illustrates Top Element mode. The reference pattern points define the hole positions to be drilled. The machining depth takes into account the normal distance between the reference points and the selected part surface.

Bottom Plane

If a bottom plane is selected, the machining depth is the distance between the hole origin and its projection on the bottom plane. This machining depth is computed for each hole in the machining pattern.

The depth shown in the geometry panel is the machining depth computed for the first hole. The Machine different depths setting is ignored when a bottom plane is selected.

Origin Offset

You can specify an Origin Offset in order to shift the entire tool path by the specified amount.

Jump Distance

The jump distance allows an extra clearance for moving in Rapid motion between the holes to be drilled whenever this distance is greater than the approach clearance.For example, for an approach clearance of 2.5mm and a jump distance of 10mm, the extra clearance is 7.5mm.

Holes at Different Levels

For 2.5-axis operations, the program automatically manages holes at different levels using horizontal transition paths.

Machining Different Depths

When dealing with design feature holes in design patterns, both the result and specification mode are taken into account (except Spot Drilling, Counterboring, and Countersinking operations).

Select the Machine different depths checkbox when you want the program to automatically manage different depths of holes in a pattern (result mode).

If the checkbox is not selected, the program uses the values specified in the Geometry tab page for the pattern holes (specification mode).

For Threading operations, select the Machine different thread depths checkbox when you want the program to take the real thread depth of each selected pattern hole into account.

Relimiting Hole Origins

The Relimit hole origin and Machine different depths checkboxes can be used together to manage the machining strategy of different design hole configurations.

In the following figures the red star ( ) represents the origin of the selected design hole, and the green star ( )

represents the start of the tool path.

Relimit hole origin OffMachine different depths Off

Relimit hole origin OffMachine different depths On

Relimit hole origin OnMachine different depths Off

Relimit hole origin OnMachine different depths On

Machining Different Diameters

It is possible to machine different hole diameters in a Circular Milling operation thanks to the Machine different diameters checkbox on the Geometry tab page.

If selected, the diameter specified for each position of the machining pattern is machined.Otherwise, the diameter of the first position of the machining pattern is used for all the pattern holes.

Managing Blind and Through Holes

A Machine Blind/Through checkbox is provided in the Geometry tab page for axial machining operations.

If selected, the blind/through characteristic of the hole is determined for each position of the machining pattern.If not selected, the blind/through characteristic of the first position of the machining pattern is used for all the pattern holes.

Note that the Machine Blind/Through capability is not available for user features.

Macros in Axial Machining Operations

The Macro tab page in the operation definition dialog box allows customized transitions paths for:

● approach

● retract

● linking

● clearance, which can be used to define the feedrate on the horizontal path between two machining positions.

All types of macros used in Drilling Operations are collision checked. If a check element is specified between two machined positions, a linking macro is applied to avoid collisions. Check (or fixture) elements as well as an associated Offset on Check can be specified in the Geometry tab page.

Note that some specific axial machining operations support additional macro types:

● global approach and global retract (Circular Milling and Thread Milling)

● return between levels (Circular Milling only)

● return in a level (Circular Milling only).

Please refer to Define Macros on an Axial Machining Operation for more information.

Editing CYCLE Syntaxes in Axial Machining Operations

For all axial operations the Edit Cycle icon in the Axial Machining Operation dialog box allows you to:

● display the unresolved syntax of the NC Instruction of the operation. This is the syntax as specified in the PP table referenced by the current Part Operation.

● display and, if needed, modify the syntax that is resolved either by geometric selection and user entries.

For example, the Cycle Syntax Edition dialog box appears when you select the Edit Cycle icon in the Boring operation

dialog box. It displays the default cycle syntax for the Boring operation.


You can access all the cycle syntaxes contained in the current PP table for a Boring operation by means of the PP instruction

icon .

For example, if your PP Table contains the following NC Instructions for Boring operations:

/*START_NC_INSTRUCTION NC_BORING_1*START_SEQUENCECYCLE/BORE,%MFG_TOTAL_DEPTH,%MFG_CLEAR_TIP*END*END/*START_NC_INSTRUCTION NC_BORING_2*START_SEQUENCECYCLE/BORE,%MFG_TOTAL_DEPTH,%MFG_CLEAR_TIP,%MFG_BREAKTHROUGH*END*END/*START_NC_INSTRUCTION NC_BORING_3*START_SEQUENCECYCLE/BORE,%MFG_TOTAL_DEPTH,%MFG_PLUNGE_OFFST,%MFG_CLEAR_TIP,%MFG_FEED_MACH,%MFG_FEED_RETRACT*END*END/*START_NC_INSTRUCTION NC_BORING_4*START_SEQUENCE CYCLE/BORE,%MFG_TOTAL_DEPTH,%MFG_PLUNGE_OFFST,0,%MFG_CMP_DWL_TIME,%MFG_CLEAR_TIP,%MFG_FEED_MACH,%MFG_SPNDL_MACH,ON,0,0,%MFG_FEED_RETRACT *END*END

Then these syntaxes will be displayed in the PP Words Selection dialog box that appears:

You can then select the desired syntax and click Apply to display it in the Cycle Syntax Edition dialog box. Just click OK to use the cycle syntax in the Boring operation being edited.

Note that in the example above, the PP Table contained several PP Instructions for the same operation type: NC_BORING_1 to NC_BORING_4.

Note that only one cycle syntax (delimited by *START_SEQUENCE / *END keywords) is allowed for each PP Instruction.

In this way, a multiple choice of syntaxes is proposed at programming time.

For more information please refer to Insert PP Instruction.


Machining PatternsThe information in this section will help you create and use machining patterns. It deals with the following topics:

● Pattern/Operation Data Hierarchy

● Pattern Data Edition

● Pattern Data Share.

Pattern/Operation Data Hierarchy

A machining pattern comprises two sets of data:

● Pattern geometry: hole positions/axes, top element

● Pattern usage or technology data: Ordering mode, Jump distance, local entry/exit distances, local depth, activate/deactivate status.

Pattern geometry is visible in the User Interface and can be handled separately through its dedicated editor.

The share of information between Pattern geometry/technology data and machining operation is available in all pattern list views:

● Manufacturing View (sorted by Patterns)

● Manufacturing View (sorted by Machining Features)

● Pattern Selection.

The presentation is similar in all views but properties associated to the elements differ:

● Manufacturing View (sorted by Patterns or by Machining Features): data edit/share functionalities at each hierarchy level (right-click)

● Pattern Selection: only Pattern geometry is selectable, other hierarchic data is shown for information.

The general presentation is as follows:

In the example above, the 3 machining operations share the same geometry but control it thru their own technology data (for example, specific Jump Distances).This is the way to overload technology data on the same position/axis data: this data will not be moved to the operation data structure.

Pattern Data Edition

Edition Levels

All Pattern data is accessible thru the operation, when the data is not shared.

Pattern geometry and/or technology data is accessible depending on whether it is shared by other Pattern technology data and/or Operations.

The Pattern editor can be accessed as follows.

● by double clicking a Pattern Geometry entity in Manufacturing View: edition at Geometry level. If the Pattern geometry is shared, all modifications will be propagated. Pattern technology data is not shown.

● by double clicking a Machining Pattern entity in Manufacturing View: edition at technology data level. If the Pattern technology data is shared, all modifications will be propagated. If the underlying geometry is not shared, it may be modified here.

If the geometry is shared, only Jump Distance and Pattern Ordering mode can be modified in the Machining Pattern dialog box. However, modifications could be done on the Pattern Geometry entity.

● when inserting a new Pattern: geometry and technology data is always accessible.

Selection of Design/ Machining Pattern Positions

Existing Design/Machining patterns can be used during geometry edition to add all their positions to the current Pattern Geometry.

● Selection of a Design pattern: all positions of the Design pattern are referenced in current one.

● Selection of a Pattern geometry: all positions are copied from the selected one.

Pattern Data Share

Pattern Selection in Operation

The reference of the whole Machining pattern thru the combo list in the Machining Operation Editor implies its complete share.If another operation already references a Machining Pattern, all the pattern's technology data and geometry will be shared.

Copy/Paste of Patterns and Operations

Copy/Paste of a Machining Pattern or a Machining Operation not only duplicates the data of the current copied entity but also all the child entities.

A Copy from current command is also available in the Machining Operation Editor's list of Patterns combo.

There are other ways to invoke Operation Copy/Paste (rigt-click in PPR view, for example).

New from Current of Patterns and Operations

In the Manufacturing View, sorted by Patterns or by Machining Features, a local copy mode called New from current duplicates the data of the current entity and manages the share of its child/father entities:

● At pattern geometry level: copies it and creates a new father Pattern Definition

● At pattern definition level: copies it and shares the same child Pattern Geometry.

A New from current command is available in Machining Operation Editor's list of Patterns combo.

Pattern Data Share Examples

The various cases of pattern data share and duplication are detailed below.

1. Manufacturing View: Copy/Paste Machining Pattern.1:

- Pattern Geometry.1 duplicated- Machining Pattern.1 duplicated - Original hierarchy kept- No pattern data share.

2. Machining Operation Editor: Copy from current (current = Machining Pattern.1):

- Pattern Geometry.1 duplicated- Machining Pattern.1 duplicated - Original hierarchy kept- No pattern data share.Allows modifying pattern data of current operation without impacting other operations.

3. Manufacturing View: Copy/Paste Drilling.1 Operation:

- Pattern Geometry.1 duplicated- Machining Pattern .1 duplicated - Operation Drilling.1 duplicated - Original hierarchy kept

- No pattern data share.4. Manufacturing View: New from current (current=Pattern Geometry.1):

- Pattern Geometry.1 duplicated- new Pattern technology data created with default values (no isolated Pattern geometry in model)- No pattern data share.

5. Machining Operation Editor: New from current (current=Machining Pattern.1):

- Pattern Geometry.1 is shared- Machining Pattern.1 duplicated Allows modifying pattern technology data in current operation without impacting other operations.

6. Manufacturing View: New from current (current=Machining Pattern.1):

- Pattern Geometry.1 is shared- Machining Pattern.1 duplicated.

How to Generate CUTCOM SyntaxesThis document explains how to generate Cutter compensation (CUTCOM) instructions for Profile Contouring, Pocketing, and Circular Milling operations.

In the Strategy tab page of the machining operation editor, Output type allows you to manage the generation of CUTCOM instructions in the NC data output:


● 2D Radial profile: both the tool tip and cutter profile will be visualized during tool path replay. Cutter compensation instructions are automatically generated in the NC data output. An approach macro must be defined to allow the compensation to be applied.

● 2D Radial tip: the tool tip will be visualized during tool path replay. Cutter compensation instructions are automatically generated in the NC data output. An approach macro must be defined to allow the compensation to be applied.

● None: cutter compensation instructions are not generated in the NC data output. In this case, the following method should be used.

Cutter Compensation on Prismatic Machining Operations

The activation/deactivation of cutter compensation is available by using NC macros on these operations.

For Profile Contouring operations, compensation can be defined on Approach, Retract, Return to finish pass, and Return between levels macros for each pass.

For Circular Milling operations, compensation can be defined on Approach, Retract, and Return between levels macros for each pass.

For Pocketing operations, compensation can be defined on Retract, Return to finish pass, and Return between levels macros on the side finish pass only.

This is done by insertion of a dedicated PP instruction in macro tool path. In the generated APT source CUTCOM syntaxes are inserted as follows:

● CUTCOM/LEFT or CUTCOM/RIGHT (from point where CUTCOM is activated).The valuation LEFT or RIGHT is automatically defined by the system in order to respect the machining side.

● CUTCOM/OFF (from point where CUTCOM is deactivated).

Methodology

Select position in macro for Cutter Compensation

In the Macro tab page of the Machining operation edition dialog box:

● In the Macro Management frame, right-click the Approach line and select the Activate contextual command.

● In the Current Macro Toolbox frame, select the desired mode. A sensitive icon representing this approach motion is displayed.

● Right-click the point where Cutter compensation is to be inserted in the macro path and select the PP Word List contextual command.

Insert CUTCOM PP word in the macro● The PP Word Selection dialog box appears.

Select the icon to access the PP word table.

Note that this icon is accessible only if a machine and an associated PP table are defined on the part operation.

● The PP Word Selection Assistant appears.Select the Major word CUTCOM in the list (Major words with parameters).

● Select the appropriate NC_CUTCOM syntax: ❍ NC_CUTCOM_ON activates Compensation.

CUTCOM/LEFT or CUTCOM/RIGHT will be generated in the APT source.The valuation LEFT/RIGHT is automatically defined by the system in order to respect the machining side.

❍ NC_CUTCOM_OFF deactivates Compensation. CUTCOM/OFF will be generated in the APT source.

● Select Apply to add the syntax then Close to quit the dialog box.

● The PP Words Selection dialog box appears again.

Click OK to insert the NC_CUTCOM_ON PP word in macro tool path.

Complete the machining operation definition

Define the other parameters of the operation (geometry, tool, and machining strategy).Click OK on the Machining operation edition dialog box to create the operation.

Shortcut with a Machining Process

To avoid defining each time macros with cutter compensation syntaxes, a template of the operation can be defined in a Machining Process.

This operation, which has macros but no geometry, can be instantiated from a catalog in the machining program. Then only the geometry and tool need to be selected to completely define the operation.

Refer to Create a Machining Process and Apply a Machining Process for more information.

Use Tolerances on Hole Design Features for Machining Processes

This task shows how to use tolerances on hole design features to apply a Machining Process with tolerancing considerations such as:● validate a Reaming operation for an H7 hole

● find a tool using a tolerance range

● parameterize Circular milling parameters according to minimum and maximum values.

This capability makes use of the Functional Tolerancing & Annotations TPSPackage Knowlegdeware package. You can load this package under Tools > Options > General > Parameters and Measures. In the Knowledge tab page, select the Load extended language libraries checkbox and choose TPSPackage as the package to load.See Functional Tolerancing & Annotations User's Guide for more information.

1. Select File -> Open then select the Tolerances.CATPart document.

The part is displayed in the Part Design workbench.

2. Double click a tolerance of one of the toleranced holes (for example, Diameter 10 H7).

The Limit of Size Definition dialog box appears.

For the selected Diameter 10 H7 tolerance, the tabulated values are set to H7 and 0 / 0.018mm as minimum / maximum values. Click OK to quit the dialog box.

These values can be accessed in Knowledgeware expressions using the following functions:

● SemanticDimTabValue for the Hole quality (H7 in the example above)

● ToleranceMin (or SemanticDimLowerLimit) for the minimum value (0mm in the example above)

● ToleranceMax (or SemanticDimUpperLimit) for the maximum value (0.018mm in the example above).

These functions can be used in Machining Processes (for example: ../startup/Manufacturing/Processes/MPWithToleranceControl.CATProcess).

The following steps are done in a Machining workbench.

Glossary

A

approach macro

Motion defined for approaching the operation start point

auxiliary command

A control function such as tool change or machine table rotation. These commands may be interpreted by a specific post-processor.

axial machining operation

Operation in which machining is done along a single axis and is mainly intended for hole making (drilling, counter boring, and so on).

B

back and forth Machining in which motion is done alternately in one direction then the other. Compare with one way.

bottom plane A planar geometric element that represents the bottom surface of an area to machine. It is normal to the tool axis.

C

clearance macro

Motion that involves retracting to a safety plane, a linear trajectory in that plane and then plunging from that plane.

climb milling Milling in which the advancing tool rotates down into the material. Chips of cut material tend to be thrown behind the tool, which results to give good surface finish. Compare with conventional milling.

conventional milling

Milling in which the advancing tool rotates up into the material. Chips of cut material tend to be carried around with the tool, which often impairs good surface finish. Compare with climb milling.

D

DPM Digital Process for Manufacturing.

E

extension type

Defines the end type of a hole as being through hole or blind.

F

Facing operation

A surfacing operation in which material is removed in one cut or several axial cuts of equal depth according to a pre-defined machining strategy. Boundaries of the planar area to be machined are soft.

Fault Types of faults in material removal simulation are gouge, undercut, and tool clash.

feedrate Rate at which a cutter advances into a work piece. Measured in linear or angular units (mm/min or mm/rev, for example).

fixture Elements used to secure or support the workpiece on a machine.

G

gouge Area where the tool has removed too much material from the workpiece.

H

hard A geometric element (such as a boundary or a bottom face) that the tool cannot pass beyond.

high speed milling (HSM)

Functionality that is supported for Pocketing and Facing operations in which corners and transitions in the tool path are rounded to ensure a smooth and continuous cutting effort.

I

inward helical Machining in which motion starts from a point inside the domain to machine and follows paths parallel to the domain boundary towards the center of the domain. Compare with outward helical.

island Inner domain of a pocket that is to be avoided during machining. It has a closed hard boundary.

L

linking motion Motion that involves retracting to a safety plane, a linear trajectory in that plane and then plunging from that plane.

M

machine rotation

An auxiliary command in the program that corresponds to a rotation of the machine table.

machining axis system

Reference axis system in which coordinates of points of the tool path are given.

machining feature

A feature instance representing a volume of material to be removed, a machining axis, tolerances, and other technological attributes. These features may be hole type or milling type.

multi-level operation

Milling operation (such as Pocketing or Profile Contouring) that is done in a series of axial cuts.

O

offset Specifies a virtual displacement of a reference geometric element in an operation (such as the offset on the bottom plane of a pocket, for example).An offset value can be greater than, less than, or equal to zero. It is measured normal to the referenced geometry or in a specific direction such as axial or radial. For example, a 5mm Offset on Contour means that a virtual displacement is applied normal to the contour geometry. A 5mm Axial Part Offset means that a virtual displacement is applied to the part geometry along the tool axis direction.Compare with thickness.

Point to Point operation

A milling operation consisting of a sequence of elementary tool motions between points. A tool motion can be defined by:

● the point the tool tip has to reach (Goto Point motion)

● positioning the tool in contact with a part element, a drive element and possibly a check element, while taking To/On/Past conditions into account (Goto Position motion)

● a relative displacement (Go Delta motion).
