Example 2 of oscillation with synchronized actions

Task
No infeed must take place at reversal point 1. At reversal point 2, the infeed must take place at
distance ii2 from reversal point 2; the oscillation axis must wait at this reversal point until partial
infeed has been executed. Axis Z is the oscillation axis and axis X the infeed axis.

Comment
; Define variable for reversal area 2
; explain reversal points 1 and 2
; Reversal point 1: Exact stop fine
Reversal point 2: Exact stop fine
; Feed for oscillating axis, feed for infeed axis
; Switch off oscillation motion at reversal point 2
After delete distance-to-go, spark-out and end position
Approach appropriately after delete distance-to-go
Approach reversal position
; 3 sparking-out strokes
; End position = 70
; Set reversal point range
; permit oscillation for Z axis
