A.) A cutting operation is performed on a piece of metal. The rake angle of the tool, α, is eight degrees. The tool penetrates the work to a depth of 8mm. The chips generated from this cut are 20mm thick. Calculate the shear plane angle, Φ, in the orthogonal model for this operation. Give your answer in degrees B.) For the same cutting operation, the cutting and thrust forces are measured. The cutting force is measured as 1600N, and the thrust force is measured as 1300N. The width of the cut is 4mm. What is the shear stress applied by the tool? Give your answer in MPa.

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.
