Q4_ Low carbon steel having tensile strength of 300 MPa and shear strength of 220 MPa is cut in turning operation with cutting speed 3 m/s. Feed is 0.2 mm/rev and the depth of cut is 3 mm. the rack angle of the tool is 5° i direction of chip flow. The resulting chip ratio is 0.45. Using the orthogonal model as an approximation turning determine: 1. Shear plane angle. Solve questions 4 and 5 2. Shear force. 3. Cutting force and feed force.

Q4_ Low carbon steel having tensile strength of 300 MPa and shear strength of 220 MPa is cut in turning operation with cutting speed 3 m/s. Feed is 0.2 mm/rev and the depth of cut is 3 mm. the rack angle of the tool is 5° i direction of chip flow. The resulting chip ratio is 0.45. Using the orthogonal model as an approximation turning determine: 1. Shear plane angle. Solve questions 4 and 5 2. Shear force. 3. Cutting force and feed force. Q5_ Turning operation uses a cutting speed 3330 mm/s, feed 0.25 mm/rev. the thermal diffusivity of the W.P material is 20 mm2/s and volumetric specific heat is 3.5 x1O^-3 J/mm^3.C cutting temperature measured by a thermocouple to be 700 °C, ambient temperature is 20 °C. Calculate the specific energy of the work material.
