| Abstract: | Sheet metal forming processes experiences very complicated deformation affected by process parameters. One of the important parameters is the blank shape, which has a direct relationship with the quality of the deformed parts. For a long time, design methods for the blank shape have been widely studied by many researchers. This paper presents a systematic introduction to the approaches of determining the optimum blank shape, discusses the presently existed problems and the researching orientation in the future. |
