Abstract

The chapter delves into the influence of punch geometry and friction on forming conditions in cold backward cup extrusion, a process crucial for manufacturing lightweight hollow parts in the automotive industry. It discusses the optimal punch nose shapes and friction coefficients to enhance material flow and reduce forming pressure. The study employs FEM analysis and experimental validation to provide a detailed understanding of these factors, highlighting the importance of lubricant conditions and material properties in achieving efficient and effective forming processes.
