Reference diameter G120
G120 determines the reference diameter of the unrolled lateral
surface. Program G120 if you use CY for G110 to G113. G120 is a
modal function.
Zero point shift, C axis G152
G152 defines an absolute zero point for the C axis (reference:
Reference point, C axis). The zero point is valid until the end of the
program.
