CYCLE4073 - longitudinal grinding with continuous infeed

Syntax
CYCLE4073(<S_A>, <S_B>, <S_W>, <S_U>, <S_K>, <S_H>, <S_A1>, <S_A2>)
Parameters
No.
Function
The cycle is used for the execution of <S_H> infeeds. The infeed from the start to the end and
from the end to the start can be different.
Sequence
1. Start of the cycle at the current position of the oscillating axis with infeed depth 0
2. Traversing of the oscillating axis with the grinding width P3 <S_W> as travel path and
feedrate for transverse infeed P5 <S_K> with continuous increase in the infeed depth up
to the infeed depth at the start P1 <S_A>.
3. Sparking out with the sparking-out time P4 <S_U>.
4. Traversing of the oscillating axis with the grinding width P3 <S_W> as travel path to the
starting point and feedrate for transverse infeed P5 <S_K> with continuous increase in the
infeed depth up to the infeed depth at the end P2 <S_B>.
5. Sparking out with the sparking-out time P4 <S_U>.
The sequence cannot be interrupted by a single block.
The sequence is repeated according to the number of programmed repetitions P7 (<S_H>).
