Coordinate System
On the lathe, the origin is typically:
- X - Radial axis (diameter or radius)
- Z - Longitudinal axis (length)
- Z origin - On the front face of the workpiece
- X origin - On the center of rotation (spindle axis)
Tip: Always leave stock allowance on diameter and length for facing and finishing.
