The shear strength of a certain work material =50,000 lb/in2. An orthogonal cutting operation isperformed using a tool with a rake angle = 20o atthe following cutting conditions: cutting speed =100 ft/min, chip thickness before the cut = 0.015 in,and width of cut =0.150 in. The resulting chipthickness ratio = 0.50. Determine (a) the shearplane angle, (b) shear force, (c) cutting force andthrust force, and (d) friction force.
