Abstract

Friction factor plays decisive role in the overall integrity of metal forming processes. As the friction during deformation influences the applied load, product shape, surface quality, internal structure, it is of paramount importance to know its influential parameters .In this investigation, the friction factor at unlubricated and Lubricated conditions with SAE 40 oil, Molydenum Disulphide, Graphite as lubricant at different temperatures has been analyzed. Among the lubricant, it is found that molybdenum-disulphide acts as a good lubricant at various temperature. Experiments were conducted to determine the friction factor, subsequently the true stress, true strain curves were developed to ascertain the K and n value’s. Further, the ANSYS 8.0 software was used to simulate the experimental conditions using power law. The finding indeed gives clear clarification that the variation of inner diameter between physical modeling and Finite Element model is less than 8%.
