Deep drilling with chip removing cycle performs rapid approach to the safe level and repeated drilling according to specified cut-in depth value <ZI> and withdrawal <Zi> values.

Cycle includes:
- Rapid travel to the <Z safe> level.
- Work feedrate travel to the <Zl>.
- Rapid retract to the <Z safe> level.
- Rapid travel to the <Zl> - <Zi> level.
- Work feedrate travel to the <Zl> + <Zi> level.
- Rapid retract to the <Z safe> level.
- Rapid travel to the 2*<Zl> - <Zi> level.
- Work feedrate travel to the <Zl> + <Zi> level.
- Rapid retract to the <Z safe> level.
- Repeat until the hole depth level is reached.
- Rapid retract to the <Safe plane> level.
