G92: Reference Point Shifting
It is used to set the current position of the axes to the specified values. With this command, the shifted coordinate system shifts all part zeros (G54~G59.4). The shift values are persistent and must be manually cleared.

Format: |
G92 X_ Y_ Z_ A/B/C_ U/V/W_ |
X: The absolute coordinate at which the X-axis is intended to be set
Y: The absolute coordinate at which the Y-axis is intended to be set
Z: The absolute coordinate at which the Z-axis is intended to be set
A/B/C: The absolute coordinate at which the A/B/C axes are intended to be set
U/V/W: The absolute coordinate at which the U/V/W axes are intended to be set
Example:
G00 G53 Z0. (Z AXIS REFERENCE)
M3 S1000 (SPINDLE CW ROTATION)
G90 G00 X150. Y50. (RAPID MOVEMENT TO X150 Y50 POINT)
G92 X100. Y100. (SHIFT COORDINATE SYSTEM)
G90 G00 Z10. (RAPID MOVE TO Z SAFE POSITION)
G01 Z-1. F500 (ENTER THE WORKPIECE AT F500)
Y550. F1000. (PERFORM CUTTING AT F1000 UNTIL Y550.)
X350. (PERFORM CUTTING AT F1000 UNTIL X350.)
Y100. (PERFORM CUTTING AT F1000 UNTIL Y100.)
X100. (PERFORM CUTTING AT F1000 UNTIL X100.)
G00 G53 Z0. (GO TO Z AXIS REFERENCE)
M5 (SPINDLE STOP)
