EXTCYCLE DEEP - Lathe drilling with chip removing cycle
Deep drilling cycle with tool retraction for chip removing DEEP(153) is used to machine axial holes by a static tool. The cycle includes:
- Rapid motion to safe plane level S.
- Travel to the return level R.
- Travel to the previous iteration depth (equals the hole top level for the first iteration) with the deceleration Dc.
- Work feedrate motion to the length L distance.
- Dwell for the specified time.
- Return to the return level R.
- Repeat steps 3 - 6 until the full hole depth is reached.
- Rapid retract to the safe plane level S.

Access from .NET
This cycle has no dedicated family handler - it is delivered through the base OnExtCycle (dispatch on cmd.CycleType / cld[2]). See Extended cycle (EXTCYCLE).
