CYCLE DRILL(163) - G81 drilling cycle
Kept for compatibility. CYCLE is retained only for compatibility with older postprocessors. Current versions of the CAM system generate the extended cycle command EXTCYCLE instead: it offers more capabilities and lets the CAM system fully simulate all of the cycle's nested motions, which CYCLE does not. Output of CYCLE can still be turned on in the CAM system settings, but this is not recommended.
G81 simple drilling canned cycle performs drilling with rapid approach to the safe level and consequent retraction to the safe plane.
Cycle includes:
- Rapid travel to safe Z level.
- Work feedrate travel to Z min level.
- Rapid travel to Safe plane level.
