A slab milling operation is performed on the top surface of a tool-steel workpiece 450 mm long by 7.5 cm wide. The helical milling cutter, which has an 80 mm diameter and seven teeth, is set up to overhang the width of the part on both sides. Cutting speed is 4000 mm/min, feed is 0.015 cm/tooth, and depth of cut = 0.60 cm. Determine (a) the actual machining time to make one pass across the surface and (b) the maximum metal removal rate during the cut. (c) If an additional approach distance of 0.05 m is added at the beginning of the pass, and an overtravel distance at the end of the pass equal to the cutter radius plus 0.0115 cm, what is the duration of the feed motion
