Turning Speed and Feed Calculator

Cut diameter (in):


Cutting speed (SFM) × 12	÷	Cut diameter (in) × π	=	Spindle speed (RPM)
Cutting feed (IPR)	×	Spindle speed (RPM)	=	Feed rate (IPM)

Cut length (in)

÷

Feed rate (IPM)

=

Cut time (min)

Turning Horsepower Calculator

Feed rate (IPM)

×

Radial depth of cut (in)

×

Cut diameter (in) × π
× π

=

Material removal rate (in³/min)

Material removal rate (in³/min)	×	Unit power (hp/in³/min)	=	Spindle horsepower (hp)
Spindle horsepower (hp)	÷	Machine efficiency (%) / 100	=	Motor horsepower (hp)
Spindle horsepower (hp) × 63,030	÷	Spindle speed (RPM)	=	Spindle torque (in∙lb)

Turning Surface Roughness Calculator

Cutting feed (IPR) ²	÷	Tool nose radius (in) × 24	=	Ra surface roughness (μin) ÷ 1000000
Ra surface roughness (μin)	×	1.11	=	RMS surface roughness (μin)
