Japanese Patent JPS629848
Kind Code:
A
Abstract:
A method and apparatus for holding an electrically conductive workpiece in a machine tool by forming at least one positioning cavity or recess on a face of the workpiece by a holder having a tip used for machining the cavity or recess by a conventional EDM sinking operation. Subsequently to forming the cavity, the tip is used as one of the holding members for the workpiece. Two tips may be used to sink cavities or recesses on opposite surfaces of the workpiece, or the tips may take the form of fingers sunk into the workpiece from one side only. The tips form part of support members mounted on the end of displaceable arms for enabling the workpiece to be positioned relative to a tool or to be displaced. The tip-provided supports may be used for supporting a portion of the workpiece being cut off or severed from the workpiece.
