Abstract

WEDM is not a traditional machining process. The process is based on a thermo-electrical energy system. In this process, any mechanical connection between the electrode (wire) and the workpiece is not required for cutting any object. To establish a contact within the wire and the work object, different dielectric fluids are used. Generally, this approach refers only to conductive materials (such as silver, copper, iron, brass, bronze). Once the deionized water flows, metal ions are released from the workpiece, and electrons are released from the wire and formed a spark between the wire and workpiece. The range of the temperature produced due to this action lies in between 8000 ℃ and 12,000 ℃. Due to this reason, the material is removed from the substrate. This article is about the investigation of the previous research work done on the different deionized water and its effect on the different output parameters acquired. From this study, researchers will be equipped with the summarized way to how to select the input parameters and enhance the output parameters using deionized water in the WEDM machining process.
