Deep drilling with chip breaking <CYCLE BRKCHP(288)>
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 <Zi> withdrawal value and <Dwell>.
Work feedrate travel to the <Zl> + <Zi> level.
Rapid retract to the <Zi> withdrawal value and <Dwell>.
Repeat until the hole depth level is reached.
Rapid retract to the <Safe plane> level.
