A straight grinding wheel has a 200 mm diameter that removes a layer of metal with a depth of 0.05 mm. An individual grain on the periphery of the wheel moves at a tangential velocity of 1800 m/min, while the work piece moves at a velocity of 30 m/min. Calculate un-deformed chip thickness and un-deformed chip length. Take the number of cutting points per unit area, C = 2 per mm2 and the ratio of chip width to average un-deformed chip thickness, r = 15. Sketch the diagram to show the machining parameter. c) Explain four design considerations for grinding.
