Abstract：

The blank estimation analysis system of sheet metal forming was developed on Pro/E platform．Based on Pro/E environment，finite element model can be directly transformed from CAD model without any parameterized modeling feature loss to achieve the CAD/CAE seamless integration．The blank shape and the formability of the sheet forming could be predicted from the geometry of the designed part，which was based on inverse approach．In product design phase，the system could work as an assitant tool for product design engineers and process engineers to predict blank unfolding．The system structure was discussed and several key technologies on Pro/E platform during program development were futher studied，such as mesh generation，constraints，process model setting，material library and project data saving．Through the experiment，the result shows that the system is feasible and accurate．
