Calculo de las RPM
Calculo de la Velocidad de Corte en el S. D.
n = Vc x 1000/ 3.1416 x D
n = Vc x 320 / D
Calculo de la Velocidad de Corte en el .S I.
n = Vc x 12/ 3.1416 x D
n = Vc x 4 / D
Ejemplo: Calcule las rpm requeridas para el torneado de acabado de una pieza de acero de maquina de D = 2"
( la Vc del acero es de 100 pie / min)
n =100 x 4 / 2 = 200 rpm

Ejemplo:Calcule las rpm requeridas para el torneado de acabado de una pieza de maquina de D = 45 mm (la Vc de acero es de 30 m / mm)
n =30 x 320 / 45 = 213.3 rpm
