I thought that you were going to make it on manual machinery. CNC is cheating for a hobby forum, ha-ha. Nice work !
I didn't have the heart to tell you last night. It only took about 55 minutes to run the part. It would have taken hours on a rotary table. Thank you for the kind words.I thought that you were going to make it on manual machinery. CNC is cheating for a hobby forum, ha-ha. Nice work !
Good question! There were several considerations.Jim, I don't know why I haven't asked this earlier, LOL, but why a stepping motor ?
I get it ! Thanks -I can tell you that this is a hand fed, cut-to-length operation. The parts are short and are fed to a hard stop, hence the need for maximum open time. The operator only has to keep some pressure on the end of the material as it is cut on the other end. Ultimately I will completely automate the process, but the customer is not ready for that step at this time.
If this was a progressive operation I would be doing things a lot different. I have a strip out of a progressive die sitting here on the table, it has about 20 stations and 14 of them actually perform an operation. I just got that one back together the other day.
You can see it running here.I didn't even think of "valve floating" (just an example of the problem that Tony mentioned,) ! Are you using an angled roller follower ? I can't WAIT to see that thing running
Thanks, Jim.You can see it running here.
I developed 3 different cam profiles, and I suspect on the last one that when I drew the circle for the max diameter, I typed in the wrong value and just didn't catch it. It works, but is not exactly what I wanted.I still don't get the high cam lift though, wonder why ...
Sure, but why did the customer specify the lift, that still sounds strange to me ? (Ignore if this is proprietary.)I developed 3 different cam profiles, and I suspect on the last one that when I drew drew the circle for the max diameter, I typed in the wrong value and just didn't catch it.

Thank you Andre.Very nice! Are you building the bottom die as well? I apologize if I may have missed that question in this thread.
