Milling Speeds and FeedsCharts Choose the material to be machined from the left side of the chart. Choose the correct FPT for that material based on the diameter of your mill. FPT is in inches per tooth (IPT) or... Choose the proper chip load factor (CLF) based on the radial depth of cut. Now ...
Milling Speed and Feed Calculator. Determine thespindle speed (RPM) and feed rate (IPM) for a milling operation, aswell as the cut time for a given cut length. Milling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth, such as an end mill or face mill. Calculations use the desired tool diameter, number of teeth, cutting speed, and cutting feed, which should be chosen …Get Price

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.Get Price
