A slab milling operation is performed on the top surface of a steel rectangular workpiece 12.0 inlong by 2.5 in wide. The helical milling cutter, which has a 3.0 in diameter and ten teeth, is set upto overhang the width of the part on both sides. Cutting speed is 125 ft/min, feed is 0.006in/tooth, and depth of cut = 0.300 in. Determinea. the actual machining time to make one pass across the surface andb. the maximum metal removal rate during the cut. c. If an additional approach distance of 0.5 in is provided at the beginning of the pass (beforecutting begins), and an overtravel distance is provided at the end of the pass equal to thecutter radius plus 0.5 in, what is the duration of the feed motion.
