A face milling operation is used to machine 6.0 mm from the top surface of a rectangular piece of aluminum 300 mm long by 125 mm wide in a single pass. The cutter has four teeth (cemented carbide inserts) and is 150 mm in diameter. The cutting speed = 2.8 m/s, and chipload = 0.27 mm/tooth. Assuming that the cutter enters the workpiece from its short side and follows a path that is centered over the workpiece, determine: i) the actual machining time to make the pass across the surface and, ii) the maximum metal removal rate during cutting.

Machining Processes and Machine Tools

Machining is represented as the process in which an excessive amount of substance is eliminated from the particular element in the form of pieces. In machining, cutting tools such as rotary tools, lathe, drill press, grinder, chop saw, welders, and many more are applied to get the desired shape. As compared to other manufacturing processes, machining is precise and versatile.

Question

d) A face milling operation is used to machine 6.0 mm from the top surface of a rectangular
piece of aluminum 300 mm long by 125 mm wide in a single pass. The cutter has four teeth
(cemented carbide inserts) and is 150 mm in diameter. The cutting speed = 2.8 m/s, and
chipload = 0.27 mm/tooth. Assuming that the cutter enters the workpiece from its short side
and follows a path that is centered over the workpiece, determine:
i) the actual machining time to make the pass across the surface and,
ii) the maximum metal removal rate during cutting.

across the surface and (b) the maximum metal removal rate during cutting A slab milling operation is performed on the top surface of a steel rectangular workpiece 12.0 in long by 2.5 in wide. The helical milling cutter, which has a 3.0 in diameter and ten teeth, is set up to overhang the width of the part on both sides. Cutting speed is 125 ft/min, feed is 0.006 in/tooth, and depth of cut = 0.300 in. 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 0.5 in is provided at the beginning of the pass (before cutting begins), and an overtravel distance is provided at the end of the pass equal to the cutter radius plus 0.5 in, what is the duration of the feed motion.
