Just a starting point. Rigidity of machine tool, work holding etc affect these numbers. Use the lower end of the range provided as a starting point.
These are for HSS and M42 (Cobalt) tools. Chart HSS & Cobalt
For Carbide try these Chart Carbide
RPM=SFM x 3.82 / cutter diameter
Feed in IPM= RPM x chip load x number of flutes
