Low carbon steel having a tensile strength of 300 MPa and a shear strength of 220 MPa is cut in a turning operation with a cutting speed of 3.0 m/s. The feed is 0.20 mm/rev and the depth of cut is 3.0 mm. The rake angle of the tool is 5 in the direction of chip flow. The resulting chip ratio is 0.45. Using the orthogonal model as an approximation of turning, determine (a) the shear plane angle, (b) shear...

Manufacturing of Engineering 21.1. In an orthogonal cutting operation, the tool has a rake angle=15°.The chip thickness before the cut = 0.30 mm and the cut yields a deformed chip thickness = 0.65 mm. Calculate (a) the shear plane angle and (b) the shear strain for the operation. 21.2 In Problem 21.1, suppose the rake angle were changed to a α= 0°. Assuming that the friction angle remains the same, determine (a) the shear plane angle, (b) the chip thickness,...
