Zero point shift, C axis G152

G152 defines an absolute zero point for the C axis (reference: MP
1005, .. “Reference point, C axis”). The zero point is valid until the end
of the program.

Standardize C axis G153

G153 resets a traverse angle >360° or <0° to the corresponding angle
modulo 360°—without moving the C axis.

Angle (spindle position) of the new C-axis zero point

G153 is only used for lateral-surface machining. An
automatic modulo 360° function is carried out on the face.
