Example of asynchronous oscillation

Exercise
The oscillation axis Z must oscillate between -10 and 10. Approach reversal point 1 with
exact stop coarse and reversal point 2 without exact stop. The oscillation axis feedrate must
be 5000. 3 sparking-out strokes must be executed at the end of the machining operation
followed by approach by oscillation axis to end position 30. The feedrate for the infeed axis is
1000, end of the infeed in X direction is at 15.
