Milling Speed and Feed Calculator How to Calculate

Milling feed rate is determined by the type of cutting tools, surface finish desired for milling parts, power available at the spindle, the rigidity of the machine and tool setup, characteristics of the material to be cut, workpiece strength, cut width, etc.

Common Formulas for Milling Operations Speed,

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.
