Approach/retraction during roughing
Infeed depth D > 0
1. The tool first moves to the starting point calculated internally in the cycle at rapid traverse.
2. The tool cuts a groove in the center of infeed depth D.
3. The tool moves back by D + safety clearance with rapid traverse.
4. The tool cuts a groove next to the first groove with infeed depth 2 · D.
5. The tool moves back by D + safety clearance with rapid traverse.
6. The tool cuts alternating in the first and second groove with the infeed depth 2 · D, until
7. All subsequent groove cuts are made alternating and directly down to the final depth T1.
Approach/retraction during finishing
1. The tool first moves to the starting point calculated internally in the cycle at rapid traverse.
