Milling Formulas. Speed (RPM) = (SFM x 3.82) / D; Feed (IPM) = RPM x FPT x Z; SFM (Surface Feet per Minute) = (RPM x D) / 3.82; IPT (Inches per Tooth) = (IPM / RPM) / Z; MRR (Cubic Inches per Minute) = IPM * WOC * DOC; AFPT (@ less than 1/2 dia. WOC) = IPM x sqroot of (D / WOC) HP (Horsepower Consumption) = MRR x mf mf - steel = 1
