CYCLE BORE9(213) - G89 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.
G89 boring canned cycle performs rapid approach to the safe level, work feedrate boring with dwell at the hole depth level and work feedrate retract to the safe plane level.
G89 cycle includes:
- Rapid approach to the Z safe level.
- Work feedrate travel to the Z min level.
- Dwell.
- Work feedrate retract to the Safe plane level.
