Parametric Optimization of Warm Deep Drawing Process of 304 Stainless Steel Cylindrical Cups

The present work is a comprehensive parametric optimization of the warm deep drawing process of 304 stainless steel. The warm deep drawing process is a crucial metal forming technique that leverages elevated temperatures to enhance the material's formability and reduce defect occurrence. This study systematically investigates the influence of various process parameters, including sheet thickness, temperature, coefficient of friction, and strain rate, on the quality of the final product in order. Using the Taguchi method for the design of experiments and Finite Element Analysis (FEA) for simulation, the research aims to determine the optimal settings for these parameters. Every parameter played its part in responses. All the factors had a similar impact on the cups designed. The strain-based FLDs are prepared to study the strain levels in the process. The optimized cup was the trail 8 cup with 1 mm, 300°C, 0.02 and 1000s-1.
