Machining center, LatheModal, group 09Canned cycle cancel
⌨On machining centers
G80
- Always put it after a canned cycle. Otherwise, drilling continues at the next coordinate command
- It is also standard to include it in the safety block at the start of a program (G40 G49 G80, etc.) (Saitama University and Haas examples)
◎On lathes: Drilling canned cycle cancel (for live tooling, face drilling)
The same number means something different on lathes (FANUC-type G-code system A). Group 10.
≠Differences between controls and machines
The same code can be written or assigned differently depending on the CNC control and the machine builder. Always check your machine’s manual.
