EXTCYCLE W5DBore8 - Drilling cycle (G88)
Drilling cycle type W5DBore8(488) (G88) drills holes with rapid approach to the safe level, dwell at hole bottom level, spindle stop and manual retract to the safe plane level.
Drilling cycle G88 consist of the following steps:
- Rapid tool motion to the hole center at the Z return level.
- Rapid descend to the Z safe level.
- Work feedrate motion to the Z min level.
- Dwell at the Z min level.
- Spindle stop.
- Manual tool retract to the Z return level.
- Restore the spindle rotation direction and speed.

Access from .NET
In addition to the base OnExtCycle, this cycle is delivered through the hole-family handler OnHoleExtCycle:
public override void OnHoleExtCycle(ICLDExtCycleCommand cmd, CLDArray cld)
See Extended cycle (EXTCYCLE) for the common .NET model.
