Electrical discharge machining process works on the basic principle of spark generation and metal removed by spark erosion. EDM spark erosion is same as electric spark which burn a small hole in a piece of metal through witch it contacts. The spark generated by this process produces heat, which remove metal by erosion and evaporation.
Understanding Electrical Discharge Machining Electrical Discharge Machining EDM, once considered a "non-conventional" machining method, is now the fourth most popular machining method. The first three are milling, turning, and grinding. One of the major reasons for the turnaround is today's EDM machines have dramatically increased their cutting ...

Electric Discharge Machining (EDM) PPT Download In wire electrical discharge machining (WEDM), also known as wire-cut EDM and wire cutting, a thin single-strand metal wire, usually brass, is fed through the workpiece, submerged in a tank of dielectric fluid, typically deionized water.
A CNC electric discharge machine (EDM) uses highly controlled electrical sparks to manipulate materials into a desired shape. It can also be called spark eroding, die sinking, spark machining or wire burning. A component is placed under the electrode wire, and the machine is programmed to emit an electrical discharge from the wire which ...
