Full-surface machining with counter spindle
G30: The expert program switches the kinematics of the
counterspindle. In addition, G30 activates the mirroring of the Z axis
and converts other functions (e.g. circular arcs G2, G3).
G99: The expert program shifts the contour and mirrors the
coordinate system (Z axis). Further programming of G99 is normally
not required for machining the rear face after rechucking.
Example: The workpiece is machined on the front face, transferred
to the counter spindle through an expert program and machined on
the rear face.
The expert program is used for:
Angle-synchronous workpiece transfer to the counter spindle
Mirroring traverse paths in the Z axis
Activating a conversion list
Mirroring the contour description and shifting for the 2nd setup
