Abstract：

The drawing process without BHF of shallow square boxes with larger corner radius was simulated by FEM technology and its results are analyzed and compared with tests. The rule that blank corner dimensions influence on the height shaped during the drawing process of square boxes is investigated. The results indicate that in order to ensure the pre-shaped height of parts formulas with correction should be used when the unfold sizes of blank are calculated.
