Optimization of tool path in two points incremental forming

Asymmetric sheet incremental forming is a relatively recent sheet metal forming process introduced to reduce the costs of sheet metal forming when low volume batches or customized parts or prototypes have to be manufactured. In recent years, this forming process saw a very rapid development, thanks to the international researches conducted by many international research centers. The present work deals with the optimization of the tool path in two point sheet incremental forming, with a full die in a particular asymmetric sheet incremental forming configuration. The aim of the study was the experimental evaluation of the tool path, which is able to reproduce an automotive component with the best dimensional accuracy, the best surface quality and the lowest sheet thinning.
