6.9 Zero Point Shifts
6.9 Zero Point Shifts
Zero point shift G51
G51 shifts the workpiece zero point by "Z" (or "X"). The shift is
referenced to the workpiece zero point defined in setup mode (see
“Defining the workpiece zero point” on page 50).
Even if you shift the zero point several times with G51, it is still always
referenced to the workpiece zero point defined in setup mode.
The workpiece zero point defined with G51 remains in effect up to the
end of the program, or until it is canceled by another zero point shift.
Parameters
X shift (diameter value)
Z shift
Example: G51

Danger of collision!
Cycle programming: With DIN macros, the zero point
shift is reset at the end of the cycle. Therefore, do not use
any DIN macros with zero point shifts in cycle
programming.
