G54 Absolute zero offset 1
Fagor 8055 8065 G-code · Mill and lathe
Selects part zero 1 from the zero offset table, measured from machine zero. G55, G56 and G57 are offsets 2 to 4. G58 and G59 are additive offsets added on top.

How it works
Modal. G54 to G57 replace each other. G58 or G59 add to the active one.
Example program
G54 (PART ZERO 1)
G00 G90 X0 Y0 Z1.0 (MOVE TO PART ZERO)
G55 (PART ZERO 2, SECOND VISE)
G00 X0 Y0 (MOVE TO SECOND PART)
G00 G90 X0 Y0 Z1.0 (MOVE TO PART ZERO)
G55 (PART ZERO 2, SECOND VISE)
G00 X0 Y0 (MOVE TO SECOND PART)
Example is in inch. Check offsets and clearances first.
Watch out for
- G58 and G59 add to G54 to G57. They do not replace them.
- G159 N1 to N20 gives more offsets on the 8055.
- G92 also shifts part zero. Do not mix them without care.
