Abstract

The part and process design for deep-drawn parts has traditionally been a trial-and-error procedure performed by experienced designers. Section analysis is part of an effort to put this task on a more scientific basis. The program presented here is capable of providing crucial design information such as the required forming force and the expected sheet thinning in a very short time. It replaces the expensive and time consuming tool tryout by computer simulation. The benefits of this approach are especially pronounced for multi-stage deep-drawing operations. Due to the simplicity of the section-analysis program, it can be used without large investments in user training. Furthermore, it can be run on PC platform, and thus, it does not require high-end computer hardware.
