Use to cancel drill, tap, and bore canned cycles (G81 to G89). 

Basic drilling cycle, generally used for center drilling or hole drilling 
that does not require a pecking motion.

counter bore drill cycle, generally used for counter boring.

Peck drilling cycle, generally used for peck drilling relatively 
shallow holes.

Tapping canned cycle, used for tapping holes.

Boring cycle, generally used to make a pass in each direction on 
a bore, or to tap with a self-reversing tapping head.

Boring cycle that allows the X-axis to back off the bore surface 
after the spindle has stopped and oriented itself.

Chip-breaker peck-drilling cycle, generally used to peck-drill 
medium to deep holes.

Boring cycle, generally used to program a pass in each direction

Shifts the location of Absolute Zero to a preset location. The 
preset location, measured from Machine Home, is specified in the 
G92 command.

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.

Used to define a window in relation to the X and Y machine home 
and the Z part zero.

Used to remove bottom stock left by a previously programmed 
pocket cycle.

Used to remove side stock left by a previously programmed
