Coordinate System Offsets

Chapter 11

11-14

Once the work coordinate system is offset, all absolute positioning
commands in the program are executed as coordinate values in the offset
coordinate system.

Example 11.5

Work Coordinate System Offset (G92)

Program Block

Comment

X25.Y35.;

rapid move to X25, Y35 in the G54 work coordinate
system.

G92X10.Y10.;

Redefines current axis position to have the
coordinates X10, Y10

Note that the zero point of the offset G54 work coordinate system will be
10 units away from the current tool location in both the X and Y directions.
If the Y value had not been entered in the G92 block, the Y coordinate
location would have remained unchanged (Y35.)
