Oscillation
11.1 Asynchronous oscillation (OS, OSP1, OSP2, OST1, OST2, OSCTRL, OSNSC, OSE, OSB)
Examples
Example 1: Oscillating axis to oscillate between two reversal points
Oscillating axis Z is to oscillate between position 10 and 100. Reversal point 1 is to be
approached with exact stop fine, reversal point 2 with exact stop coarse. The feedrate for the
oscillating axis must be 250. 3 sparking-out strokes must be executed at the end of the
machining operation and the oscillating must approach end position 200. The feedrate for
the infeed axis must be 1 and the end of infeed in the X direction should be reached at
position 15.
