Abstract:An integrated optimal design method for the maximum drawing length (drawing limit) of stainless steel in hydro-mechanical deep-drawing is proposed. In this paper, three steps are adopted. The Finite Element Method based on the concept of the Taguchi technique is first used to simulate the processes of deep drawing at the considerations of all the possible significant parameters to the drawing limit, and then the parameters that have the convex curves on S/N diagram are chosen for optimal experimental designs according to the Taguchi experimental Method. On the last step, the hybrid of the artificial neural network with the genetic algorithm is used to find the optimal value from these parameters. With this solution, an experiment is fulfilled and compared. It is shown that the result obtained from the hybrid method is good agreement with experiment.
