Esteemed RCM'ers: I'm designing a part that'll be produced on a CNC lathe and am looking for "design for manufacturing" help from anyone who has more knowledge of CNC lathes than I (that's about everyone, since I have never worked with a CNC lathe).
Here's the design as it stands:
1) pick up knurling tool, knurl
2) RH tool, shape crown, then bevel for next knurl
3) LH tool, finish head enough to cut face groove
4) some tool, cut face groove
5) LH tool, finish profile of part
6) thread tool, thread
7) parting tool, part off
That seems like a lot of tool changes.
- Any ideas on simplifying this? design tweaks to make it easier?
- Are the 0.010" fillets I have drawn reasonable (not too small)?
- suggestions for SS material to specify that will be easy to machine and have a nice finish?
TIA for any thoughts, dean
This is the pivot for an improved lid shutter on my (Joeveo) coffee mugs. Bosses are to be staked to retain the wave spring washer and the shutter. I'll be looking for a shop to make these too--get in touch if you'd like to quote.
