Abstract: | The most important activity of metal forming technology is the correct design of stages geometry for economic consideration in order to increase the metals utilization coefficient and the productivity realized products with high dimensional accuracy and a finer quality of worked surface.In this Study the rotation of local coordinate by using finite element method through (M. S. C / Nastran ) are investigating with influencing of some parameters such as , Reduction area , Simi die angle and friction factor to obtain the stresses and strains developed during the drawing process of polygonal section from round section .The results show that its possible to use the technique of rotation of local Coordinate in all programs of ( F.E.M ) to analysis metal forming process especially when the friction factor = 0.1 , Simi die angle = 9, Reduction area =35% which are gives good agreement to the results of ( U.B.T )and the practical results. |
