Electrical discharge machining (EDM) is one of the most widely disseminated manufacturing technologies, in particular as regards the generation of accurate and complex geometrical shapes on hard metallic components. Nevertheless, current EDM has major limitations when dealing with fine surface finish and material removal rate. Recently EDM with powder mixed dielectric (PMEDM) has been a focus of intense research work in order to overcome these technological performance barriers. The present study is done with an objective to modify the machining characteristics like surface roughness,...

Use of cutting fluids in metal cutting enhances machining performance. However, the use of cutting fluids results in problems such as high cost, pollution and hazards to operators health. To overcome the problems related to the use of cutting fluids, researchers have made efforts to search for some alternatives to minimize or even avoid the use of cutting fluids in machining operations. MQL is one of the safe and environment friendly alternatives sought to reduce the use of coolant lubricant fluids in metal cutting.
