Finite Element Analysis and Experimental Comparison During Highly Precision Progressive Die Process

This research aims to apply the technology to simulate the conditions of forming methods by finite element analysis and design helped to produce highly precision progressive die of the auto part. BACK PLATE FR R/L auto part selected in case study made from steel grade JAC270C, 1.8 millimeter of thickness. To study the stamping simulation with finite element. It was found that the workpiece can formed without causing risk of tearing workpiece. In the design process with the stamping station on precisions progressive die. And also has created a series of die highly precisions progressive die stamping and test specimens. The results showed that defects on a specimen. Then solve a series die in such a position and repeat the test. Moreover, specimens from the process of stamping the size and surface according to the results of finite element analysis. However, in the range of acceptable under certain conditions. The results of the simulation using a finite element compared to the experimental results with accuracy of 97%. As well as to reduce the losses and costs of the testing process, including to improve the accuracy of the functions of die effectively.
