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
that does not require a pecking motion.
Basic Drill Cycle
G82
counter bore drill cycle, generally used for counter boring.
counter bore Drill Cycle
G83
Peck drilling cycle, generally used for peck drilling relatively
shallow holes.
Peck Drill Cycle
G84
Tapping canned cycle, used for tapping holes.
Tapping Cycle
G85
Boring cycle, generally used to make a pass in each direction on
a bore, or to tap with a self-reversing tapping head.
Boring Bidirectional Cycle
G86
Boring cycle that allows the X-axis to back off the bore surface
after the spindle has stopped and oriented itself.
Boring Unidirectional Cycle
G87
Chip-breaker peck-drilling cycle, generally used to peck-drill
medium to deep holes.
Chip Break Cycle
G89
Boring cycle, generally used to program a pass in each direction
with a dwell at the bottom.
Flat Bottom Boring Cycle
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
preset location, measured from Machine Home, is specified in the
G92 command.
Zero Set
G100
G100 programmed with axis (G100 X) activates “mirror image”
(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.
Mirroring
G120
Used to define a window in relation to the X and Y machine home
and the Z part zero.
block form
G133
Used to remove bottom stock left by a previously programmed
pocket cycle.
Bottom Finish
G134
Used to remove side stock left by a previously programmed
pocket cycle.
Side Finish
G162
This cycle allows islands in irregular pockets.
