The top surface of a rectangular work part is machined in a peripheral milling operation. The work part is 730 mm long by 50 mm wide by 95 mm thick. The milling cutter, which is 66 mm in diameter and has 4 teeth, overhangs the width of the part equally on both sides. Cutting speed = 50 m/min, chip load = 0.25 mm/tooth, and depth of cut = 7.4 mm. Determine the time required (in minutes) to make one pass across the surface, given that the setup and machine settings provide an approach distance of 5 mm before actual cutting begins and an overtravel distance of 22 mm after actual cutting has finished.
