Full-surface machining with single spindle
G30: Normally not required
G121: The expert program mirrors the contour. Further programming
of G121 is normally not required for machining the rear face after
rechucking.
Example: Describes the machining of the front and rear face, using
one NC program. The workpiece is first machined on the front face;
then it is rechucked manually. The rear face is machined
subsequently.
The expert program mirrors and shifts the contour for the 2nd setup.
