Turning Operations 3


36/16936

SolidCAM enables you to perform the following types of Turning operations.

The turning geometry has to be located in the ZX-planein the Z+region and can be dened directlyon the solid model.

Turning Operation

This operation enables you to turn a longitudinal prole ora face prole. The resulting tool path can either use the turningcycles of the CNC-machine, if they exist, or generate all of the

tool movements. In case the tool movements are generated by the

program, the minimum tool movements length is generated taking

into account the material boundary at the beginning of the particular

operation. The prole geometry is adjusted automatically by the

program, if needed, because of the tool shape, to avoid gouging thematerial.

Drilling Operation

Geometry definitionregion


37/169

3. Turning Operati

Grooving Operation

This operation enables you to perform a groove either on a

longitudinal geometry (internal or external) or on a face geometry.

The resulting tool path can use a single machine cycle, generate all the

tool movements (G0, G1) or generate several machine cycles.

Drilling Operation

This operation enables you to perform a drilling action at the rotationaxis. There is no geometry denition for this type of operation sinceit is enough to dene the drill start and end positions.

Threading Operation

This operation enables you to perform threading. The threading can be

either longitudinal (internal or external) or facial. This operation can be

used at present only if the CNC-machine has a thread cycle. SolidCAM

outputs the tool path for the threading exactly with the same length as

the dened geometry without any checking for material collision.


38/16938

Angled Groove operation

This operation enables you to perform inclined grooves. The geometry

dened for this operation must be inclined relative to the Z-axis ofthe CAM-Part Coordinate System. The Tool angle parameter enables

you to adjust the angle of the tool cutting the material.

Cut off operation

This operation enables you to perform cutoff machining. This operation

is used to cut the part or to perform a groove whose width is exactlythe same as the tool width. The cutting can be performed using CNC-

machine cycles; chamfers and llets can also be generated.

Face turning operation

This operation enables you to perform turning of facial proles. The principal working directionis the X-axis direction.

For a more detailed explanation of Turning operations, refer to the SolidCAM Turning User Guide.
