Problem 1 The top surface of a rectangular work part is machined in a peripheral milling operation. The work part is 735 mm long by 50 mm wide by 95 mm thick. The milling cutter, which is 65 mm in diameter and has five teeth, overhangs the width of the part equally on both sides. Cutting speed 60 m/min, chip load = 0.20 mm/tooth, and depth of cut = 7.5 mm. (a) Determine the time required 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 over travel distance of 25 mm after actual cutting has finished. (b) What is the maximum material removal rate during the cut?

2. You are manufacturing a can which is a perfect cylinder. The ideal volume of the can is 375 cm3. Since the bases of the cylinders are exactly 50 cm2, the volume of the can is V = 50h where h is the height of the can in centimeters. You need to cut the sides of the can so the volume has at most an error of 10 cm³. Give the range of heights the can could have and still meet the required specifications for its volume.
