PrefaceAdvanced Machining easily defines NC programs dedicated to machining complex 3D parts(aerospace, hydraulic, turbo-machinery, and so on) within a single workbench including 2.5 to5-axis machining technologies. Complementary to other V5 NC Manufacturing solutions andproducts, this product brings new functionalities in order to cover the entire machiningprocesses and existing key functionalities to speed up skilled oriented operations. All thesefunctionalities are grouped together to overtake previous version CATIA NC Manufacturingsolutions, and therefore surpass all existing "all in one" CAM systems.

Advanced Machining offers the following main functions:Accurate tool path definition through a full set of 2.5 to 5 axis milling and drillingmachining capabilitiesQuick tool path definition thanks to an intuitive user interfaceFlexible management of tools and tool catalogsDefinition of machining areas including multi-thickness areasCheck and repair tool holder collisionsQuick verification of tool pathIn-process part visualization and material removal simulation in multi-axis modeTool path editorFast tool path update after modificationSeamless NC data generationAutomatic shop-floor documentationManagement of NC related documentsMulti-CAD managementIntegration with DELMIANC know-how capitalization and reuseProductive design change management.

Specification TreeHere is an example of a Process Product Resources (PPR) specification tree for AdvancedMachining.

Process List is a plan that gives all the activities and machining operations required totransform a part from a rough to a finished state.

Part Operation defines the manufacturing resources and the reference data.Manufacturing Program is the list of all of the operations and tool changes performed.The example above shows that:

Drilling.1 is complete and has not been computedDrilling.2 is complete but has been computed (by means of a replay)Drilling.3 does not have all of the necessary data (indicated by the exclamationmark symbol)Drilling.4 has been deactivated by the user (indicated by the brackets symbol)Drilling.5 has been modified and needs to be recomputed (indicated by theupdate symbol).

Product List gives all of the parts to machine as well as CATPart documents containingcomplementary geometry. Resources List gives all of the resources such as machine or tools that can be used in theprogram.

GlossaryA

approachmacro

Motion defined for approaching the operation start point

auxiliarycommand

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

axialmachiningoperation

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

Bback 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.

Cclearancemacro

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

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

CombinParelm

Tool axis guidance strategy for Multi-Axis Flank Contouring. This strategycombines three phases:

tool fans over a given Leave distancetool is tangent to the drive surface at a given Contact height and follows thesurface isoparametricstool fans over a given Approach distance.

Combin Tanto Tool axis guidance strategy for Multi-Axis Flank Contouring. This strategycombines three phases:

tool fans over a given Leave distancetool is tangent to the drive surface at a given Contact height and is containedin a plane normal to forward directiontool fans over a given Approach distance.

Contactheight

Determines a point on the drive surface where the tool must respect tangencyconditions. The Contact height is measured from the tool tip along the tool axis.The point on the drive is computed such that its projection normal to the drive ontothe tool axis respects the Contact height value. The tool pivots to respect thetangency point.

conventionalmilling

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

DDPM Digital Process for Manufacturing.

Eextensiontype

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

FFacingoperation

A surfacing operation in which material is removed in one cut or several axial cutsof equal depth according to a pre-defined machining strategy. Boundaries of theplanar 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).

Fixed Tool axis guidance strategy for Multi-Axis Flank Contouring. The tool axis is fixed.

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

pass beyond.high speedmilling (HSM)

Functionality that is available for operations such as Flank Contouring, Pocketingand Facing in which corners and transitions in the tool path are rounded to ensurea smooth and continuous cutting effort.

Iinward 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.
