12.5.2 Example 1 of oscillation with synchronized actions
Exercise
Direct infeed must take place at reversal point 1; the oscillation axis must wait until the part
infeed has been executed before it can continue traversal. At reversal point 2, the infeed
must take place at a distance of -6 from reversal point 2; the oscillation axis must not wait at
this reversal point until part infeed has been executed. Axis Z is the oscillation axis and axis
X the infeed axis. (See chapter "Controlling Oscillation via Synchronous Actions").
Note
The setting data OSCILL_REVERSE_POS_1/2 are values in the machine coordinate
system; therefore comparison is only suitable with $AA_IM[n].
