11.2 G-Code and M-Code Definitions

G-Code	Description	Label
G80	Use to cancel drill, tap, and bore canned cycles (G81 to G89).	Drilling Off
G81	Basic drilling cycle, generally used for center drilling or hole drilling	Basic Drill Cycle
	that does not require a pecking motion.
G82	counter bore drill cycle, generally used for counter boring.	counter bore Drill Cycle
G83	Peck drilling cycle, generally used for peck drilling relatively	Peck Drill Cycle
	shallow holes.
G84	Tapping canned cycle, used for tapping holes.	Tapping Cycle
G85	Boring cycle, generally used to make a pass in each direction on	Boring Bidirectional Cycle
	a bore, or to tap with a self-reversing tapping head.
G86	Boring cycle that allows the X-axis to back off the bore surface	Boring Unidirectional Cycle
	after the spindle has stopped and oriented itself.
G87	Chip-breaker peck-drilling cycle, generally used to peck-drill	Chip Break Cycle
	medium to deep holes.
G89	Boring cycle, generally used to program a pass in each direction	Flat Bottom Boring Cycle
	with a dwell at the bottom.
G90	Sets 3500i to Absolute Mode.	Absolute
G91	Sets 3500i to Incremental Mode.	Incremental
G92	Shifts the location of Absolute Zero to a preset location. The	Zero Set
	preset location, measured from Machine Home, is specified in the
	G92 command.
G100	G100 programmed with axis (G100 X) activates “mirror image”	Mirroring
	(ON) for that axis. Mirror image reverses the sign (+/-) of
	subsequent numbers. More than one axis can be mirrored at once
	(G100 XY). To cancel mirror image, program G100 on a block by
	itself.
G120	Used to define a window in relation to the X and Y machine home	block form
	and the Z part zero.
G133	Used to remove bottom stock left by a previously programmed	Bottom Finish
	pocket cycle.
G134	Used to remove side stock left by a previously programmed	Side Finish
	pocket cycle.
G162	This cycle allows islands in irregular pockets.	Islands
