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.

Electrical discharge machining produces surfaces with a fine finish and high precision. Moreover, EDM allows users to machine hardened workpieces. Whereas other machining techniques need to be executed before the workpiece is hardened with heat treatment, electrical discharge machining can be applied on the hardened material as well.
Metal-bonded diamond wheels, due to its strong grain retention and thermal conductivity properties, are generally used for grinding difficult-to-cut materials, such as high-performance ceramics. On the other hand, the poor dressability of this type of bond limits its application. This study aims to evaluate the use of a wire electrical discharge machining (EDM) principle for truing and ...
Wire Cutting Electrical Discharge Machining: The use of thin wires to cut objects can also be referred to as wire erosion, wire burning EDM. In this type, the wire is used as an electrode, and the wire is continuously fed from the automatic feed with the spool during processing.
