Abstract：

Material formability and drawing limit could be improved by the optimization of blanks and production cost also could be reduced. The deep drawing of double-box was chosen as the example to optimize blank by the inverse and forward finite element methods. The optimized blank was smaller than the original one. The drawing limit height and the productions quality were improved by the optimized blank in the finite element analogy and contrast experiments with the same situations. The results show that the finite element analogy is effective and accurate when it is used in the blank optimization of complex box drawing.
