9.4 Oscillating cycles (CYCLE4071 ... CYCLE4079)
Sequence
1. Start of the cycle at the current position of the oscillating axis.
2. Traversing of the infeed axis to the infeed depth at the start P2 <S_I> with the feedrate for
infeed P6 <S_R>.
3. Sparking out with the sparking-out time P8 <S_P>.
4. Traversing of the oscillating axis with the grinding width P5 <S_A> as travel path and the
feedrate for transverse infeed P7 <S_F>.
5. Traversing of the infeed axis to the infeed depth at the end P3 <S_J> with the feedrate for
infeed P6 <S_R>.
6. Sparking out with the sparking-out time P8 <S_P>.
7. Traversing of the oscillating axis with the grinding width P5 <S_A> as travel path to the
starting point and the feedrate for transverse infeed P7 <S_F>.
8. Without cancellation: The sequence described above is repeated until the total infeed depth
P4 <S_K> has been reached. The last stroke is then distributed unevenly.
With cancellation: The machining is stopped at the start point.
The sequence cannot be interrupted with a single block.
