Function
The cycle is used for machining with a total infeed depth in infeed steps. The infeed depths at
the start and at the end 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 and/or oscillating axis is 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 and end is 0 or the total infeed depth is 0, only one
sparking-out stroke is performed.
