The present research attempts to apply to such piercing a manufacturing process using a viscoplastic pressure medium process (VM Process) previously proposed by one of the authors. The appearance of the holes pierced through copper foils is observed microscopically, and the effect of the working conditions on it is examined. Although only for a specific condition, the process is shown to be successful in piercing the circular holes of 50 μm in diameter with 75 μm in pitch, unobtainable by the conventional shearing process. Besides, a new technique (AFM method) for precise piercing applicable to general working conditions is proposed.}, pages = {2206--2212}, title = {マイクロ塑性加工に関する研究 : 多数微細穴同時加工の検討}, volume = {55}, year = {1989} }
