FA[axis]= Feed for oscillating axis
OSCTRL [axis]= (Set, reset options)
OSNSC [axis]= Number of sparking-out strokes
OSE [axis]= End position
OS [axis]= 1 = activate oscillation; 0 = deactivate oscillation
Stopping times at reversal points: OST1, OST2
Hold time Movement in exact stop area at reversal point
-2 Interpolation continues without wait for exact stop
-1 Wait for exact stop coarse
0 Wait for exact stop fine
>0 Wait for exact stop fine and then wait for stopping time
The unit for the stopping time is identical to the stopping time programmed with
G4
.
Example of an oscillating axis that should oscillate between two reversal points
The oscillation axis Z must oscillate between 10 and 100. Approach reversal point 1 with
exact stop fine, reversal point 2 with exact stop coarse. Machining is performed with feedrate
250 for the oscillating axis. Three sparking-out strokes must be executed at the end of the
machining operation followed by approach by oscillation axis to end position 200. The
feedrate for the infeed axis is 1, end of the infeed in X direction is at 15.
