Infeed at reversal point
As long as the oscillating axis has not reached the
reversal point, no movement takes place on the infeed
axis.
The following instructions are used subject to the
above assumptions:
Reversal point 1:
WHENEVER $AA_IM[Z]<>$SA_OSCILL_REVERSE_POS1[Z] DO $AA_OVR[X]=0 ->
-> $AA_OVR[Z]=100
Whenever
greater or less than
then
and
the current position of oscillating axis Z in the MCS is
the position of reversal point 1
set the axial override of infeed axis X to 0%
set the axial override of oscillating axis Z to 100%.
Reversal point 2:
For reversal point 2:
WHENEVER $AA_IM[Z]<>$SA_OSCILL_REVERSE_POS2[Z] DO $AA_OVR[X]=0 ->
-> $AA_OVR[Z]=100
Whenever
greater or less than
then
and
the current position of oscillating axis Z in the MCS is
the position of reversal point 2
set the axial override of infeed axis X to 0%
set the axial override of oscillating axis Z to 100%.
