Hi: New to app & form. Trying to understand how to use CNC Machinist calc to set up a job on a conversational lathe. I know the material, hardness & insert type & radius. Need the following: SFM Depth of cut Roughing IPR Finishing IPR

SFM can be found under "MATL SFM". Roughing D.O.C. and feed depends on rigidity and H.P., I don't yet have this in the app. Finishing IPR can be calculated if you know the surface finish that's required. This can be found under "FINISH CALC".
