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.

采用增量微成形技术在不锈钢箔（一种难加工材料）上形成了各种形状的微金字塔，并获得了特定成形条件下的成形极限。成形力表明，有必要开发一种抑制不锈钢箔回弹的成形技术，以便有效地将成形力传递到箔上并提高成形极限。还发现不锈钢箔具有与铝箔非常不同的成形极限公式。
