Generic Turning

With generic turning is covered both external and internal turning machining operations.

External Cycle : The tool moves from the outside the inner part of the component.

Internal cycle : The tool moves from the inner part of the component to outside.

Before proceed with internal cycle is necessary create a central hole in the component.

In important also use a tool with dimension compatible with this hole diameter.

You can find this information in tool catalogue .

To add this operation, from [MENU] -> Lathe  -> External or Internal Turning , depending on your needs.

See related article on how to associate geometry to an operation, and also page about [Step Profile] and [Coordinate] pattern. They are useful with generic turning operation.

Here the screen related to external / internal turning machining.

Geometry Selection

Generic turning accept as geometry both open profiles and closed profiles.

It's suggested to link just a single profile in geometry list.

Open Profile:

Closed Profile:

Turning Parameters 

Turning direction - Traditional : Tool direction it's from Z+ to Z-

Turning direction - Reverse : Tool direction it's from Z- to Z+ , you need to select a compatible tool when you change this property.

Profile Start/End Extension : A tangent extension will be added to start/end of selected geometries

Apply Fillet on sharp corner : Where applicable, a fillet will be created in sharp corner.

Toolpath Limit : With this you can define the limits of working area.

Without Limit :

With Limit :

Operation 1 of 2 : Roughing 

Finish Allowance X / Z : It's the material thickness left by the roughing tool for the finishing operation.

Roughing Macro : Where applicable , it will print G71 macro code in output code instead of simple movements

Visualized toolpath and simulation may be different from the actual toolpath generated by the machine macro. Use this option only if you are you sure of gcode correctness

Finish with same tool : Finishing allowance material will be removed by the roughing tool

Operation 2 of 2 : Finishing

Reverse direction on vertical wall : When enable , the turning direction will be inverted in 90° profile element. In some context , this may reduce tool vibration.

Vertical wall threshold : Will be considered only elements with length bigger than this value.

Multiple finishing passes : It create multiple finishing passes. The distance between passes is determined by finishing allowance thickness.

example : If you have a 0.3mm of finish allowance and 3 finish passes. Toolpath will generate 3 passes with a 0.1mm distance between them.
