Hello everyone,

Does anyone know how to properly create an eccentric (off-center) turning operation?

I have tried several approaches:

• using a coordinate system at the part center
• using an offset coordinate system

However, none of these methods result in proper synchronization between the workpiece rotation and the tool movement. The toolpath is calculated, but the motion is not synchronized with the spindle rotation as required for eccentric turning.

I would really appreciate any guidance or examples.

A demo file is attached.
