Abstract

The most key factor in the modern sheet metal process is an accurate dimension of final shape part. The accurate simulation of the drawing products will not be useful since springback will occur after the tools are removed off the drawing die set. One of the most promising ways to solve this problem is modify the die surface as known die compensation. Die compensation is one of the hottest topics in the stamping field. In this paper, a new method to compensate the die tool shape due to elastic deviation is proposed. The combination of spring-forward and spring-back method is applied simultaneously. This method was applied to 2D draw bending benchmark problem from Numisheet ’93 for verification. The simulation result show that the final deformed part is closely to the desired shape part
