Abstract

For conventional stamping, appropriate process can be applied on top and bottom die to enhance the performance and efficiency of the forming process. But it is difficult and expensive for the conventional stamping to form high strength large spring-back thin sheet components of complex shape in small batch. In an effort to improve forming precision and to minimize the cost, a novel spinning and pressing forming (SPF) method is presented in this paper. The forming performances, including forming forces and surface roughness, were evaluated with the processes of forming titanium alloy and Aluminum alloy sheets. Reduced forming forces, lower tool wear, improved surface roughness and lower cost were observed using SPF. The investigation illustrates a great potential of applying SPF for improving shape precision and reducing the cost.
