[7 marks]Amild steel tubing of 50 mm outside diameter is turned on a lathe with cutting speed of 20 mpm(meter per min.)with a tool having rack angle of 35. The tool is given a feed of 0.10mm/rev. and it is found by dynamometer that the cutting force 250 Kg and feed force 100 Kg. Length of continuous chip in one revolution 80 mm and width of chip 2 mm.
