Chapter 15: 1. Shear plane angle and shear strain: In an orthogonal cutting operation, the tool has a rake angle = 16°. The chip thickness before the cut = 0.32 mm and the cut yields a deformed chip thickness = 0.72 mm. Calculate (a) the shear plane angle and (b) the shear strain for the operation. 2. Shear strength: The cutting force and thrust force have been measured in an orthogonal cutting operation to be 301 lb and 291 lb,...
