Geometrical Defect Evaluation of Cold Embossing AA6061 Based on FEA and Physical Modeling Technique

Abstract

Geometrical defect plays a significant role to inaccuracy of the cold forging part. Defect will harm the assembly tend to affect the performance of the part. Therefore, it must be detected and minimized it as soon as the manufacturing begins. The paper presents an investigation on the geometrical defect of the cold embossing pin based FEA and physical modeling methods. The study focuses on the effect of distance to the edge (DTE) to bulging geometries. The results of both methods show a good agreement.
