EDM with Mesh-sheet Electrode

This paper describes a new method ofEDM with mesh-sheet electrode. Mesh-sheet of copper wire has splendid advantages of electrode making with its high ductility and malleability. First, EDM properties of mesh-sheet to zinc alloy have been examined to use as an electrode of machining. Mesh-sheet electrode gives very stable process, since generated debris and gas are excluded quickly through the woven wires. The expectation of lower electrode wear ratio to workpiece was also confirmed experimentally. Comparing to usual solid electrode made it clear that this method was very efficient in terms of machining speed and process. FinaIIy, a practical machining by means of meshsheet electrode was tried to make 3-dimensional molding die.
