Calculate hp required at spindle and primary cutting force


A turning operation calls for a single pass on a 3" diameter part down to 2.800" on a lathe using a HSS (High Speed Steel) right-hand tool. The length of the cut along Z axis is 3.500". The material is a low carbon steel (BHN of 200) with a suggested cutting speed of 85 fpm at .015 ipr. Use a specific HP of 1.1 HP/in3/min.

Calculate the following:

a) Depth of cut

b) RPM

c) Feed in (ipm)

d) cut time

e) MRR

f) HP required at the spindle

g) Primary cutting force (Fc)
