Zero point shift G51
G51 displaces the workpiece datum by ”Z” (or ”X”). The shift is
referenced to the workpiece datum defined in setup operation.
Even if you shift the zero point several times with G51, the
displacement is still always referenced to the workpiece zero point
from the setup mode.
The zero point shift applies until the end of the program or until it is
canceled by another zero point shift.
