    That's a great suggestion! A search for others led me to this model on Thingiverse, if you have access to a 3D printer. While I don't have the need for a tool library like the OP, this tag should be...

    Probably tool diameter / 200 = fpt

    E.g., 1/2" endmill: .500 / 200 = .0025, which seems to be a reasonable starting point or rule-of-thumb. My gut tells me it'll get overly large with larger tools...

    Without a subspindle, but still on a CNC: slow down to maybe 800-1000 RPM at a diameter where the part doesn't wobble (IIRC used .200 for parts under 2.0" OD), then complete the cut at that low RPM....
