CYCLE4077 - surface grinding with infeed at the reversal point and cancel signal

Syntax
CYCLE4077(<S_GAUGE>, <S_I>, <S_J>, <S_K>, <S_A>, <S_R>, <S_F>,
<S_P>, <S_A1>, <S_A2>)
Parameters

Function
The cycle is used for machining with a total infeed depth P4 <S_K> in infeed steps. The infeed
depths at the start P2 <S_I> and at the end P3 <S_J> can be different. There is a tangential
motion between the infeeds. The depth infeed is cancelled when the cancel signal of the rapid
input is 1 or the cancel condition is satisfied. A complete stroke is performed after the
cancellation.
The positional data P2 to P5 can be negative or positive.
The specification of the infeed axis P9 <S_A1> and/or oscillating axis P10 <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 P2 <S_I> and at the end P3 <S_J> is 0 or the total
infeed depth P4 <S_K> is 0, only a sparking-out stroke is performed.
