The following data are available from orthogonal cutting experiments. The depth of cut (feed) to = 0.13 mm, width of cut b 2.5 mm, rake angle a = - 5°, and cutting speed V = 2 m/s. Chip thickness, te (mm) = 0.23 Cutting force, F. (N) = 430 Thrust force, F; (N) = 280 Determine the shear angle ð, friction coefficient u , shear stress t, shear strain y on the shear plane, chip velocity Ve, and shear velocity V, as well as energies uf ,ug, and u .
