9.4 Oscillating cycles (CYCLE4071 ... CYCLE4079)
5. Traversing of the infeed axis to the infeed depth at the end P3 <S_B> with the feedrate for
infeed P6 <S_I>.
6. Sparking out with the sparking-out time P5 <S_U>.
7. Traversing of the oscillating axis with the grinding width P4 <S_W> as travel path to the
starting point and the feedrate for transverse infeed P7 <S_K>.
8. Without cancellation: The sequence described above is repeated until the number of
programmed repetitions P7 (<S_H>) is reached.
With cancellation: The machining is stopped when the next start point is reached.
The sequence cannot be interrupted by a single block.
