ABSTRACT
Several researches investigated effect of various components on the final quality of fabricated parts through deep drawing process using statistical methods. But there is no specific research about impression of effective process parameters in different geometries, including symmetrical, asymmetrical, curved, flat or angular and clarification of qualified design requirements of this parameters according to the product geometry. Most of the research about effective parameters on deep drawing process and the quality of the products have been on special geometries and there is no appropriate information on sheet metal forming mechanics, the condition and intensity of impression related to the parameters in other geometries. In this article we have tried to investigate the effectiveness and the importance level of six different parameters on the least final thickness of the fabricated part in deep drawing process using punches whit symmetrical and asymmetrical geometries through Taguchi method in the design of Experiments (DOE). The parameters under study include a portion of the most important blank mechanical properties, forming devices and deep drawing process. The results have been achieved by simulations in Abaqus software and have been verified through experimental tests.
