To carry out perfectly the forming analysis of the extruding products, it is necessary that the friction boundary condition between dies and blanks should be worked out the accurate numerical friction models. But, the existing numerical models of the extrusion may be large different from the actual conditions. In this study, accurate analysis of the extrusion forming for the variation of pressure and velocity should be subjected. It is to develop the accuracy of the numerical friction models and potentialize to apply for the high speed forming work in the extrusion. Therefore, the results should improve the accuracy, cause the energy saving for the extrusion and finally expand the applying areas of the results.
