Mild steel is being machined at a cutting speed of 200 m/min with a tool rake angle of 10°. The widths of cut and uncut thickness are 2 mm and 0.2 mm respectively. If the average value of coefficient of friction between the tool and the chip is 0.5 and the shear stress of the work material is 400 N/mm2, determine
(i) Shear angle and
(ii) cutting and thrust components of the machining force.
