5. The tool then drills with spindle speed S as far as the next infeed depth.
6. Steps 2 to 5 are repeated until the programmed final drilling depth Z1 is reached.
7. On expiry of dwell time DT, the tool is retracted with spindle speed SR to the safety
clearance. The spindle stops and retracts to the retraction plane.
Approach/retraction CYCLE84 - without compensating chuck in the "chip breaking" mode
1. The tool drills at the programmed spindle speed S (dependent on %S) as far as the
1st infeed depth (maximum infeed depth D).
2. Spindle stop and dwell time DT.
3. The tool retracts by the retraction distance V2 for chip breaking.
4. The tool then drills to the next infeed depth at spindle speed S (dependent on %S).
5. Steps 2 to 4 are repeated until the programmed final drilling depth Z1 is reached.
6. On expiry of dwell time DT, the tool is retracted with spindle speed SR to the safety
clearance. The spindle stops and retracts to the retraction plane.
