An orthogonal cutting operation is being carried out under the following conditions: to = 0.1 mm, tc = 0.2 mm, width of cut = 5 mm, cutting speed V = 2 m/s, rake angle = 10, Fc = 500 N, and Ft = 200 N. Calculate (a) the shear angle +, (b) the friction force F at the rake face, (c) the chip velocity Vc, (d) the total specific energy (energy required to remove unit volume of material), (e) the percentage of the total specific energy that is dissipated at the rake face.
