Despite the increasing demands for improved product design, a limited number of works have been reported in the field of sheet metal forming. In the present study, introducing the Taguchi method, an otpimal and robust combination of parameters in found and a data base management system is utilized for knowledge acquisition. Analysis data, estimation rules of formability and graphical representation of the analysis have been employed for the dewigners understanding and evaluation. The developed system is applied to a deep drawing process. Through the present study, it is shown that the developed systerm is useful for the design and the formability estimation of sheet metal forming processes.
