Studies on a new incremental sheet metal forming process: Using geometric, fem and experiments

Abstract

Sheet metal forming is one of the most commonly used manufacturing processes. However, the conventional sheet metal forming process is expensive for prototyping and low volume production. To solve this problem, dieless forming process, also called the Incremental Sheet Metal Forming (ISMF), has become a focal point of the industry in recent years. Currently, ISMF technology is still premature and needs much research and development. This paper presents a novel ISMF process using a high frequency punch without support. This paper presents the studies of the ISMF process by geometric method, the FEM analysis and experiments. Finally, some conclusions are drawn as well as the future work. © Springer-Verlag Berlin Heidelberg 2010.
