CYCLE4079 - surface grinding with intermittent infeed

Syntax
CYCLE4079(<S_I>, <S_J>, <S_K>, <S_A>, <S_R>, <S_F>, <S_P>, <S_A1>,
<S_A2>)
Parameters
No.
Function
The cycle is used for machining with a total infeed depth P3 <S_K> in infeed steps. The infeed
depths at the start P1 <S_I> and at the end P2 <S_J> can be different. There is a tangential
motion between the infeeds.
The positional data P1 to P4 can be negative or positive.
The specification of the infeed axis P8 <S_A1> and/or oscillating axis P9 <S_A2> are optional.
If one or both parameters are not specified, the cycle uses the first two geometry axes of the
channel.
If the sum of the infeed depth at the start P1 <S_I> and at the end P2 <S_J> is 0 or the total
infeed depth P3 <S_K> is 0, only a sparking-out stroke is performed.
