Example 11.9 demonstrates the G92.1 offset cancel.
Example 11.9
G52 Offset Cancelled By a G92.1
Program Blocks Comment
N1 G01Y25.X25.; move to Y25, X25
N2 G52Y10.X10.; work coordinate system is offset by Y10, X10
N3 Y25.X25.; move to Y25, X25 in the offset coordinate system
N4 G92.1; G52 offset is cancelled, program position displays axis position
at X35Y35.

The G92.2 command cancels these offsets:
G92 work coordinate system offset
{SET ZERO} offset
Jog offset
It does not:
cancel an external offset
reset the current work coordinate system (G54-G59.3)
cancel a G52 offset
