| Research Abstract |
Various shapes of micro pyramids were formed on a stainless steel foil, one of difficult-to-work material, using incremental microforming and the forming limits were obtained for specified forming conditions. Forming forces revealed that it is necessary to develop a forming technology that suppresses the springback of a stainless steel foil in order to transmit forming forces to a foil efficiently and increase the forming limit. It was also found that the stainless foil has a forming limit formulation very different from an aluminum foil.
