Infeed in reversal area
The infeed motion must start within a reversal area
before the reversal point is reached.
These synchronized actions inhibit the infeed
movement until the oscillating axis is within the
reversal area.
The following instructions are used subject to the
above assumptions:
Reversal area 1:
WHENEVER $AA_IM[Z]>$SA_OSCILL_REVERSE_POS1[Z]+ii1 DO $AA_OVR[X]=0
Whenever
greater than
then
the current position of oscillating axis in the MCS is
the start of reversal area 1
set the axial override of the infeed axis to 0%.
Reversal area 2:
WHENEVER $AA_IM[Z] <$SA_OSCILL_REVERSE_POS2[Z]+ii2 DO $AA_OVR[X]=0
Whenever
less than
then
the current position of oscillating axis in the MCS is
the start of reversal area 2
set the axial override of the infeed axis to 0%.
