Explanation
- Changing by G10
With the G10 command, each workpiece coordinate system can be
changed separately.
- Changing by G92
By specifying G92IP_;, a workpiece coordinate system (selected with a
code from G54 to G59) is shifted to set a new workpiece coordinate
system so that the current tool position matches the specified
coordinates (IP_).
Then, the amount of coordinate system shift is added to all the
workpiece zero point offset values. This means that all the workpiece
coordinate systems are shifted by the same amount.
Example
WARNING
When a coordinate system is set with G92 after an
common workpiece zero point offset value is set, the
coordinate system is not affected by the common
workpiece zero point offset value. When
G92X100.0Z80.0; is specified, for example, the
coordinate system having its current tool reference
position at X = 100.0 and Z = 80.0 is set.

If G92X100Y100; is commanded when the tool is positioned
at (200, 160) in G54 mode, workpiece coordinate system 1
(X' - Y') shifted by vector A is created.
