6. The tool cuts alternately in the first and second recess by the
infeed depth 2D until the final depth T1 is reached (3) and (4).
Between the individual recess cuts the tool moves back by D +
safety clearance at rapid traverse. After the last recess cut, the tool
is retracted at rapid traverse to the safety clearance.
7. All further recess cuts are made alternately directly down to the
final depth T1 (5) to (8). Between the individual recess cuts the tool
moves back to the safety clearance at rapid traverse.
