Investigations on the Formability of Incremental Punching Process

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2011
It was reported that the incremental sheet metal forming (ISMF) produces larger deformations as compared to the conventional forming processes. We developed a new ISMF method based on incremental punching. In this study, a theoretical method based on M-K
