1 The external workpiece zero point offset amount can
be set within +7.999 mm or +0.79999 inch for every
2 When G92 is specified after a shift value has been
specified, the shift value is ignored.
(Example) When G92X100.0Z80.0; is commanded, a
workpiece coordinate system in which present tool
position is X = 100.0, Z = 80.0 is established,
irrespective of set shift value.
3 The diameter or radius for movement along the X-axis
conforms to the diameter or radius specified in the
- Shifting workpiece coordinate system
Six workpiece coordinate systems can be shifted by a specified value
(common workpiece zero point offset value)
Workpiece zero point offset value can be changed in three ways.
(1) Using CRT/MDI panel
See Operator’s Manual (Operation).
(2) Using program (G10)
See II-7.2.4, "Changing workpiece coordinate system by
(3) Using external workpiece coordinate system shift function
An input signal to the CNC from the PMC enables you to
change the external workpiece zero point offset amount.
Refer to machine tool builder's manual for details.
