B–63172EN/01
NC FUNCTION
46
A coordinate system in which the zero point is set to a fixed point on the
workpiece, to make programming simple.
A workpiece coordinate system may be set by using one of the following
methods:
(1)Using G92
(2)Automatic setting
When (1) is used, a workpiece coordinate system is established using the
numeric value programmed after G92.
When (2) is used, a workpiece coordinate system is automatically
established upon a manual reference position return, as specified in a
parameter.
G92 _ ;IP
By using the above command, a workpiece coordinate system can be set
so that the current machine position is at a specified position.

When manual reference position return is performed, a workpiece
coordinate system can be set automatically so that the current tool
position at the reference position becomes a desired position which is set
using a parameter in advance. This functions as if G92IP__; were
specified at the reference position.
