Abstract
Uncertainty is inevitable in sheet metal metal forming process. Aleatory uncertainties in material properties, blank thickness and friction condition are inherent irreducible variabilities in sheetmetal forming. However, optimal design configurations which are obtained by conventional designoptimization methods are not always able to meet the desired targets due to the effect of uncertainties.In order to tackle this problem, a multi-objective robust design optimization (MORDO) applied forsheet metal draw bending process is introduced in this paper. In addition, since the MORDO of sheetmetal forming involves considering serveral conflicting criteria, a Pareto multiple objective criteriadecision-making approach based on capability indices is proposed.
