CYCLE BORE6(210) - G86 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.
G86 boring canned cycle performs rapid approach to the safe level, work feedrate boring to the hole depth level, spindle stop at hole depth level and rapid retract to safe plane level.
G86 cycle includes:
- Rapid approach to the Z safe level.
- Work feedrate travel to the Z min level.
- Spindle stop. If oriented spindle stop is enabled (CLD [14] parameter), it is positioning the spindle in a given angular position and then tool shifts to specified small value of the X, Y and Z coordinates.
- Rapid retract to Safe plane level.
- Restore spindle rotation direction and speed.
