7. A two-component cutting force dynamometer was used during a shaping operation on a free cutting steel. The component of the resultant cutting force in the direction of relative motion was recorded as 360N and the component perpendicular to the motion as 126N. The cutting conditions were as follows:- Feed . Width of cut 5 Cutting ratio To Cutting speed vi 58.5 μπι 3.84 mm 0.51 2.0 m/sec Calculate the shear angle, the average geometrical shear strain and the shear energy per unit volume of work material removed if the tool rake angle was 20° Comment briefly on any assumption made or implied.
