the current position of the oscillating axis in the MCS
is
reversal position 1
set the marker with index 1 to value 0 (reset marker 1)
the current position of the oscillating axis in the MCS
is
the start of reversal area 2 (here: reversal point 2 -6),
set the axial override of the infeed axis to 0%.
set the marker with index 2 to value 0 (reset marker 2)
the current position of the oscillating axis in the MCS
is
reversal position 1,
set the axial override of the oscillation axis to 0%
set the axial override of infeed axis Z to 100% (this
cancels the previous synchronous action).
the distance-to-go of the part infeed is
0,
set the marker with index 2 to value 1
set the marker with index 1 to value 1
the flag with index 2 is
1,
set the axial override of the infeed axis to 0%; this
prevents premature infeed (oscillation axis has not left
reversal point 1 yet).
the flag with index 1 is
