Shift G53/G54/G55
G53, G54 and G55 shift the workpiece zero point by the offset values
defined in setup mode.
The shift is referenced to the workpiece zero point defined in setup
mode, even if you shift the zero point several times with G53, G54 and
G55.
The shift remains in effect until the end of the program or until it is
canceled by other zero point shifts.
Before using zero point shifts with G53, G54 and G55, you need to
define the offset values in setup mode (see "Defining offsets" in the
User's Manual).
Additive zero point shift G56
G56 shifts the workpiece zero point by the defined value in the
selected axis. The shift is referenced to the currently active workpiece
zero point.
If you shift the workpiece zero point more than once with G56, the
shift is always added to the currently active zero point.
A shift in X is entered as a radius.
