A Simulation Study on Improving Formability of SUS304 Sheet Metal Deep Drawing Process

摘要

In the traditional mold manufacturing process, manual methods are mostly used to design, fabricate and then perform forming test to find out the reasonable processing mode for the product. Thanks to the development of technology, the forming design can be greatly reduced by using commercial software. This study uses a combination of ABAQUS software and TAGUCHI algorithms to calculate and design products. By using simulation tool, the fracture, safety, wrinkles as well as stress and strain on the surface of the product can be easily predicted after forming process. So that, the forming process were firstly simulated and executed on the software to find out important parameters. The variance analysis (ANOVA) was then performed to assess the effect of each parameter. Finally, the optimum solution for the product was selected based on ranking levels of each parameter.
