CYCLE4078 - surface grinding with continuous infeed

Syntax
CYCLE4078(<S_I>, <S_J>, <S_K>, <S_A>, <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> by means of continuous
infeed. The infeed depths from the start to the end P1 <S_I> and from the end to the start P2
<S_J> can be different.
The positional data P1 to P4 can be negative or positive.
