##### How do you calculate spindle speed ...

How do you calculate spindle speed? The following equation is used to cal-culate spindle speed: rpm = sfm ÷ diame-ter × 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).
