Re: [CAD_CAM_EDM_DRO] Sizing servo motors for BP size mill

I remember speaking to Ian from AHHA about Bridgeport style mills and he
said around 2N/m continuous and 6N/m peak if I remember correctly, on a .200
pitch. That's 283.2oz/in continuous and 849.6oz/in peak, or 17.702lb/in
continuous and 53.106lb/in peak.
