9.4.3 CYCLE4072 - longitudinal grinding with infeed at the reversal point and cancel
signal
Syntax
CYCLE4072(<S_GAUGE>, <S_A>, <S_B>, <S_W>, <S_U>, <S_I>, <S_K>,
<S_H>, <S_A1>, <S_A2>)
Parameters
No.

Function
The cycle is used for the execution of <S_H> infeeds taking into account an external cancel
signal. The infeed depth can be different at the start and at the end. There is a tangential motion
between the infeeds. The depth infeed is cancelled when the cancel condition is satisfied. A
complete stroke is always performed after the cancellation of the depth infeed.
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_A> with the feedrate for
infeed P6 <S_I>.
3. Sparking out with the sparking-out time P5 <S_U>.
4. Traversing of the oscillating axis with the grinding width P4 <S_W> as travel path and the
feedrate for transverse infeed P7 <S_K>.
