The G80 command in Fanuc CNC programming is used to cancel any active drilling, boring, or tapping canned cycle (such as G81, G82, G83, G84, etc.). Once a canned cycle is active, it will keep repeating at every new X-Y coordinate until it is explicitly stopped. If not canceled, the cycle may unintentionally continue at the wrong positions, causing tool crashes or part damage.

When programming a Vertical Machining Center (VMC), certain operations like drilling, boring, tapping, and reaming are repetitive. Writing full toolpath codes (G01, G00, G02, G03) for each step would be time-consuming.
To simplify this, Fanuc controls (and most CNC controls) use Canned Cycles – pre-programmed subroutines that perform common machining operations with just one command line.
