An orthogonal cutting operation is being carried out in which uncut thickness is 0.010 mm, cutting speed is 130m/min, rake angle is 15° and width of cut is 6 mm. It is observed that the chip thickness is 0.015 mm, the cutting force is 60 N and the thrust force is 25 N. The ratio of friction energy to total energy is (correct to two decimal places) |
