WCS on Lathe Setup
To define the WCS origin in lathe setups, is enough define Z axis direction and origin z distance from world zero.
From v5.x the setup WCS is actually moved in 3D space and the related operations will be orientated with related setup WCS
Most of the times for the turning operations it will be necessary the WCS for the front side and the WCS for the back side of the component.
If any 2D or 3D geometry is available, from setup edit screen just press [Front Side] or [Back Side] to define the lathe setup,
See this image.
Pressing [Front side] the WCS will be setted in front of the part.
Meanwhile pressing the [Back Side] the lathe WCS will be setted to back of the part.
Is still possible define manually the Z Axis direction and the origin distance from coordinate world zero.
By convention, the revolution axis will be the world Z Axis.
