"Electrical discharge machining" , sometimes colloquially also referred to as "spark machining", "spark eroding", "burning", "die sinking", "wire burning" or "wire erosion", is a manufacturing process whereby a desired shape is obtained using electrical discharges . Material is removed from the workpiece by a series of rapidly recurring current discharges between two electrodes, separated by a dielectric liquid and subject to an electric voltage. One of the electrodes is called the tool-electrode, or simply the "tool" or "electrode", while the other is called the workpiece-electrode, or "workpiece".
When the distance between the two electrodes is reduced, the intensity of the electric field in the volume between the electrodes becomes greater than the strength of the dielectric ), which breaks, allowing current to flow between the two electrodes. This phenomenon is the same as the breakdown of a capacitor . As a result, material is removed from both electrodes. Once the current stops , new liquid dielectric is usually conveyed into the inter-electrode volume, enabling the solid particles to be carried away and the insulating properties of the dielectric to be restored. Adding new liquid dielectric in the inter-electrode volume is commonly referred to as "flushing". Also, after a current flow, the difference of potential between the electrodes is restored to what it was before the breakdown, so that a new liquid dielectric breakdown can occur.
The erosive effect of electrical discharges was first noted in 1770 by English physicist Joseph Priestley.
