I run into a problem when trying to post process an optimized program group (below).
As can be seen in the above picture, under the program group of CHMFRMILL_OP1, there is operation CHAMFER, several S1H_CHM_L and S1H_CHM_M. After optimizing the group, all the operations except CHAMFER were optimized and an optimization group OPTIMIZED_NC_4 was created. See the operations below. The first picture is operation CHAMFER, the second is the optimized group.
When I postprocessed the group, I can see a tool change between operation CHAMFER and OPTIMIZED_NC_4, although all the operations under this program group use the same tool. This happended even when I posted with OOTB post processor.
And the weird thing is that for the OPTIMIZED_NC_4 operation, "Auto Tool Change" and "First Move" were run.
Our expert on this topic is on vacation this week and next.
I suggest that you either create an IR for this so that we can take a look.
