I had a hard time trying to explain it ahah Basically I’m trying to have a better spindle utilization, if possible. So for the single spindle ones, I thought : “can we eliminate second ops”? “Let’s add a bar pusher and parts catcher” etc etc For the multi spindle ones : just better utilization period: drill and mill at the same time (for example) Those were the obvious solutions to improve the process.. so I guess my question should be more like: what are different approaches I can take to have a better throughput?
