【 摘 要 】

In order to ensure unbroken production in cup-shaped part deep drawing process with diverse mould assemblage, a prediction model of limiting sheet diameter based on response surface method (RSM) was presented. The simulated samples were used to fit the sheet diameter RSM prediction model, and the multiple determination coefficient of RSM was reached to 0.9. Setting the minimum sheet thickness to the critical value, the RSM will become a limiting sheet diameter prediction model. It shows a close agreement with FE simulated results through the test of examples. It can be concluded that presented RSM not only has higher efficiency, but also has higher accuracy. It will provide an early quality forecasting before actual deep drawing production.
