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).

I am trying to make sense of the books that give equations for speed (rpm) and table feed to cut aluminum (with a Bridgeport and 1/2" 4 flute endmill). From what I gather, it is: rpm = fpm*12 / pi*D so for a HSS cutter of 0.5", a 750 fpm, that gives an rpm of ~ 5900 ! (this seems too fast) Feed = ftr * T * rpm

In the case of a DC motor, the product of the square of the total motor current and the armature resistance is the power loss as heat in the armature windings. For example, if the total motor current was .203 A and the armature resistance 14.5 Ohms the power lost as heat in the windings is: power loss = 0.2032 x 14.5 = 0.59 Watts.
