Cold forge vs hot forgepros and cons
First, calculate the cutting length per min. from the feed and spindle speed. l=f×n=0.2×1000=200(mm/min) Substitute the answer above into the formula. Tc=lm÷l=100÷200=0.5(min) 0.5×60=30(sec)The answer is 30 sec.

Substitute f=.008IPR, RE=.031 into the formulae. h=(.008)2÷(8×.031)×1000=.258µinch The theoretical finished surface roughness is .258µinch.

First, calculate the cutting length per min. from the feed and spindle speed. l=f×n=.008×1000=8IPM Substitute the answer above into the formulae. Tc=lm÷l=4÷8=0.5(min) 0.5×60=30(sec) The answer is 30 sec.
Substitute f=0.2mm/rev, RE=0.8 into the formula. h=0.22÷(8×0.8)×1000=6.25µm The theoretical finished surface roughness is 6µm.
