Hey people,
I'm trying to machine the inner surface of the cylindrical workpiece, shown in the picture. The workpiece is a converted step file from a originally stl file of a 3D scan. It has no thickness and includes only triangular mesh elements. So it isn't possible to select a inner and outer surface of a triangular element. It's only possible to select the whole triangular element.
The problem is that Mastercam 2021 automatically machine the outer surface of the workpiece, as you see in the picture, when I choose the multiaxis parallel toolpath and select all the elements.
I already tried to import the workpiece with a rotation of 180°, so the inner surface is at the top. I also tried to change the WCS, the CPlane and the TPlann, but nothing worked.
Is there any option to force Mastercam 2021 to machine the inner surface, i. e. to invert the tool axis about 180°?
I would appreciate your help.
