WebJul 1, 2014 · The following equation is used to calculate spindle speed: rpm = sfm ÷ diameter × 3.82, where diameter is the cutting tool diameter or the part diameter on a lathe in inches, and 3.82 is a constant that comes from an algebraic simplifica-tion of the more complex formula: rpm = (sfm × 12) ÷ (diameter × π). Because the tool diameter is ... WebThe chip area is the radius (D/2) of the drill times the feed per revolution.; The speed starts with zero at the center of the drill and reaches its maximum at the OD.Therefore, we use the average speed, which is Vcmax/2.; In imperial units, the speed is given in SFM, and K equals12 to convert the speed into Inches/min and get the final result in Inch 3.
