(USCS units) A turning operation is performed using a rake angle of 15°. Cutting speed = 200 ft/min, feed= 0.012 in/rev, and depth of cut = 0.100 in. The chip thickness ratio measured after the cut = 0.48. Determine (a) chip thickness after the cut, (b) shear angle, (c) friction angle, (d) coefficient of friction, and (e) shear strain (USCS units) The turning operation in the previous problem involves a work material whose shear strength = 52,000 lb/in2. Based on your answers to the previous problem, compute (a) shear force, (b) cutting force, (c) thrust force, and (d) friction force.

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.
