Programming technology functions
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 P1 <S_A> with the feedrate for
infeed P5 <S_I>.
3. Sparking out with the sparking-out time P4 <S_U>.
4. Traversing of the oscillating axis with the grinding width P3 <S_W> as travel path and the
feedrate for transverse infeed P6 <S_K>.
5. Traversing of the infeed axis to the infeed depth at the end P2 <S_B> with the feedrate for
infeed P5 <S_I>.
6. Sparking out with the sparking-out time P4 <S_U>.
7. Traversing of the oscillating axis with the grinding width P4 <S_A> as travel path to the
starting point and the feedrate for transverse infeed P6 <S_K>.
The sequence cannot be interrupted with a single block.
The sequence is repeated according to the number of programmed repetitions P7 (<S_H>).
Example
Executing two oscillating motions with the following cycle parameters:
● Infeed depth at the start: 0.02 mm
● Infeed depth at the end: 0.01 mm
● Stroke: 100 mm
● Sparking-out time: 1 s
● Infeed feedrate: 1 mm/min
● Transverse feedrate: 1000 mm/min
● Repetitions: 2
● Oscillating and infeed axes: Standard geometry axes
