A face-milling operation is used to machine 5 mm from the top surface of a rectangular piece of aluminum 400 mm long by 100 mm wide. The cutter has four teeth and is 150 mm in diameter. Cutting conditions are V = 3 m/s, f=0.27 mm/tooth, and d = 5.0 mm. The cutter is centered over the rectangular workpiece. Determine (a) what is the spindle RPM? (b) what is the feed rate?

Q: i. spindle rpm ii. feed speed iii. cutting time iv. material removal rate

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.
