G80 - Cancel Drill Cycle (default)
G80 cancels any active drilling cycle. When G80 is active, X and Z motion commands
move the tool directly to the programmed endpoint without performing a drilling cycle. In
addition to turning off the drilling cycle, G80 activates Linear Motion at Rapid and clears
the modal drilling parameters such as R, Z, Q, and P.
If the drill cycle depth is not programmed after G80, then the drill cycle depth defaults to
the R plane.
Default—Yes
Modal—Yes
G00 cannot be programmed in the same block.
G81 - Drill Cycle
G81 sets drilling as the modal drill cycle.
Default—No
Modal—Yes
Cancels G74, G80, G82, G83, G84, G98, G99
The tool motion for the drill cycle is shown below.
1. Position to XZ
2. Rapid to reference plane
3. Feed to depth
4. Rapid to reference plane
