Unformatted text preview: depth of cut = 0.6mm, and the chip thickness ratio = 0.38. Determine (a) the shear strength of the work material and (b) the coefficient of friction in the operation. 6. An orthogonal cutting operation is performed using a rake angle of 15, t o = 0.012 in and w = 0.100 in. The chip thickness ratio is measured after the cut to be 0.55. Determine: (a) the chip thickness after the cut, (b) the shear angle, (c) the friction angle, (d) the coefficient of friction, and (e) the shear strain. 7. The orthogonal cutting operation described in previous Problem involves a work material whose shear strength is 40,000 lb/in2, cutting speed is 400ft/min, Based on your answers to the previous problem, compute: (a) the shear force, (b) the cutting force, (c) the thrust force, and (d) the friction force, (e) cutting power....
