CYCLE4071 - longitudinal grinding with infeed at the reversal point

Syntax
CYCLE4071(<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 <S_H> infeeds. The infeed depth at the start and at the
end can be different. There is a tangential motion between the infeeds.
