ABSTRACT:
A press machine is provided to reliably reposition a workpiece without causing it to become offset. The press machine includes a punch tool for punching a workpiece and a workpiece gripping section for gripping and moving a workpiece on a table. The workpiece gripping section repositions the workpiece. A control facilities stops the punch tool while it is penetrating the workpiece during the punching operation. In this stopped condition, the control facilities causes the workpiece griping section to perform a repositioning operation. During the repositioning operation, the control facilities selects a punch tool with a shape other than a perfect circle to fix the workpiece.
