Numerical Investigation of Punch Radius and Shape Effects on the Formability of Coated Aluminum Sheet in Deep Drawing

Deep drawing is a popular manufacturing process across many industries as it has the ability to efficiently produce complex shapes with high accuracy and repeatability. However, deep drawing is limited by various factors such as the formability of the material being used, part design, and deep drawing process parameters. The shape of the punch can also affect the deep drawing process. Finite element analysis has become an essential tool, allowing manufacturers to improve their product quality while reducing the need for expensive experimentation. By using advanced simulation techniques, our objective is to gain a comprehensive understanding of how varying punch characteristics can influence the formability and the quality of the deep-drawn components. In this study, we numerically investigate, by simulating different scenarios, the effects of punch radius and shape on the formability of coated Aluminum sheet in deep drawing process. This work is important to optimize the deep drawing process, reduce defects, and improve the efficiency of deep drawing operations of coated Aluminum sheets.
