For the companies exploiting metal forming processes the main goals are to maximization of the product quality and simultaneously minimization the waste and producing costs. Aluminum and high strength steels are the most important materials which can be used in automotive body panels in order to reduce weight, but low formability of these alloy sheets greatly limits its use in complex product designing. In this paper we used a new approach based on response surface methodology (RSM), Finite Element Method (FEM) and segmented binder for determining the optimal variable blank holder force to obtain a part with least flaws. The proposed optimization system was tested on an industrial example from SAIPA automotive industries research & innovation (AIRIC). The number of required numerical simulations using the RSM combined with the Design of Experiment was not critical but was much smaller than other conventional optimization methods. Therefore, using this approach, final optimal blank holder force can be achieved in a short time.
