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 repeating 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.
