I'm designing a 3 axis wood router. I would like to get feedback on two design aspects:
1. typical acceleration profiles: I could guesstimate this - but I'd like get some feedback on what other's use on their DIY CNCs (for all three axes).
2. loading: on the tooling: I'm not sure what a typical design load would be... how much force does it take to route through wood at 'typical' accelerations and speeds.
I'm looking at a 20" x 30" x 5" table, wood structure with ball screw drives on all three axes (Two on the X, one on the Y, one on the Z). I'm targeting NEMA 23 motors, but wondering if I can get away with less than 350 oz-in.
Any input would be appreciated.
Thanks!
