Additive zero point shift G56
G56 shifts the workpiece zero point by ”Z” (or ”X”). The displacement
is referenced to the currently active workpiece zero point.
If you shift the workpiece zero point several times with G56, the
displacement is always added to the currently active zero point.
Parameters
X, Z: Shift (X radius value) – default: 0
Parameter-dependent zero point shift G53, G54, G55
G53, G54, G55 displace the workpiece zero point by the value defined
in the setup parameters 3, 4, 5. The shift is referenced to the workpiece
zero point defined in setup operation.
Even if you shift the zero point several times with G53, G54, G55, the
displacement is still always referenced to the workpiece datum from
the setup mode.
The datum shift applies until the end of the program or until it is
canceled by another datum shift.
A shift in X must be indicated as a radius value.
