11.5.2 Example 1 of oscillation with synchronized actions
Task
Direct infeed must take place at reversal point 1; the oscillation axis must wait until the partial
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 partial infeed has been executed. Axis Z is the oscillation axis and
axis X is the infeed axis (see Section "Oscillation controlled by synchronized actions
(Page 653)).
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].
Program section
Program code Comment
; Example 1: Oscillation with synchronized actions
OSP1[Z]=10 OSP2[Z]=60 ; explain reversal points 1 and 2
OST1[Z]=-2 OST2[Z]=0 ; Reversal point 1: without exact stop
; Reversal point 2: Exact stop fine
FA[Z]=5000 FA[X]=250 ; Feed for oscillating axis, feedrate, infeed axis
OSCTRL[Z]=(1+8+16,0) ; Switch off oscillation motion at reversal point 1
; After delete DTG spark-out and approach end position
; After DTG, approach relevant reversal position
;
OSNSC[Z]=3 ; 3 sparking-out strokes
OSE[Z]=0 ; End position = 0
WAITP(Z) ; enable oscillation for the Z axis
;
; motion-synchronous actions:
;
; always, when the current position of the oscillating axis in the
; Machine Coordinate System
; not equal to reversal position 1
; then set the marker with index 1 to value 0
; (Reset marker 1)
WHENEVER $AA_IM[Z]<>$SA_OSCILL_REVERSE_POS1[Z] DO $AC_MARKER[1]=0
;
; always, when the current position of the oscillating axis in the
