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.
The workpiece is machined on the front face, transferred
Example:
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
