What is the cutting time when 100mm workpiece is machined at 1000min -1 with feed = 0.2mm/rev ? (Answer) 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.
