1) a slab-milling operation will take place on a part 300 mm long and 40 mm wide. a helical cutter 75 mm in diameter with 10 teeth will be used. if the feed per tooth is 0.2 mm/tooth and the cutting speed is 0.75 m/s, find the machining time and metal-removal rate for removing 6 mm from the surface of the part.2) refer to the following and assume that d = 150 mm, w = 60 mm, l = 500 mm, d = 3 mm, v = 0.6 m/min, and n = 100 rpm. the cutter has 10 inserts, and the workpiece material is a high-strength aluminum alloy. calculate the material removal rate, cutting time and feed per tooth.
