摘要
In order to overcome the shortcomings, such as without accurate definition and can't eliminate the errors during the forming process, of the traditional calculation method, and improve the application of the matching-rate as an indicator for quality of stamping die, a new methodology is proposed to calculate the matching-rate based on numerical simulation in this paper. The accurate definition of matching-rate and the realization algorithm are also presented. In addition, an improvement scheme is available to raise the matching-rate, which includes three main stages: calculate the matching-rate by using the numerical simulation results at first;then update the surface mesh of die with compensation values until the matching-rate achieves the standard;reconstruct the die surface with the output point-cloud data. A set of software is also self-developed to calculate the matching-rate and finally improve the quality of stamping die. An automobile panel die is set as an example to validate the proposed method.
