Principles of Electrical Discharge Machining and Non

The electrodes used in die sinker electrical discharge machining are subject to damage caused by the sparks used in machining, which causes them to melt. This damage is referred to as wear. Up until around 1964, there was only one major machining technique, which used punches.

Electrical Discharge Machining Characteristics of ECAP

Electrical discharge machining

Electrical discharge machining involves immersing the workpiece in machine liquid and removing material via melting-fusion, through the use of current discharges between two electrodes. The melting process, triggered by discharging electricity from the piece's surface, makes it work on any conductive material.

Feasibility study on production of Metal Matrix Composite (MMC) material for Electrical Discharge Machining

Electrical discharge machining (EDM) is a non-conventional machining process where material is removed electro thermally by a series of successive discrete discharges or sparks between two electrically conductive objects, which are electrode and workpiece.
