A Research on the Measurement of Friction Coefficient of Plastic Forming by Floating Die Extrusion

A new measurement of friction coefficient which is more applicable to overload extrusion technology is proposed in this paper. It determines the friction coefficient of overload plastic forming by firstly determining the load mutation of friction by a floating die experimental device. It is proved in this experiment that the friction coefficient in extrusion process can be precisely determined and the effectiveness of lubricating can be evaluated objectively by this new method which is easier to understand and master than the theory that determines the friction coefficient by ring upsetting.
