3.25.1.46 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. Parameter Data type Meaning
1 <S_GAUGE> STRING Cancel conditions for infeed:
1. Number of a rapid input
2. Logical expression
2 <S_A> REAL Infeed depth at the start
3 <S_B> REAL Infeed depth at the end
4 <S_W> REAL Grinding width
5 <S_U> REAL Sparking-out time
6 <S_I> REAL Feedrate for infeed
7 <S_K> REAL Feedrate for transverse infeed
8 <S_H> INT Number of repetitions
9 <S_A1> AXIS Infeed axis (optional) or 1st geometry axis
10 <S_A2> AXIS Oscillating axis (optional) or 2nd geometry axis
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.
