Full-surface machining with opposing 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 opposing spindle through an expert program and machined on the
rear face (see illustrations).
The expert program is used for:
 Angle-synchronous workpiece transfer to the opposing spindle
 Mirroring traverse paths in the Z axis
 Activating a conversion list
 Mirroring the contour description and shifting for the 2nd chucking
