摘要：The wire electrical discharge machining (WEDM) is one of the latest non-traditional machiningprocesses, based on thermoelectric energy between the work piece and wire. The performance of the process, to a largeextent, depends on the tool material, work piece material &manufacturing method of the tool. A suitable selection oftool can reduce the cost of machining. The performance of WEDM is find out on the basis of Material RemovalRate(MRR), KERF Width and Surface Roughness (SR). The important machining parameters of EDM which affectingon the performance parameters are discharge current, pulse on time, pulse off time, arc gap, flushing pressure, servovoltage and wire tension. Taguchi design of experiments is used to conduct experiments by varying the parametersservo voltage, pulse on time and pulse off time. The process performance is measured in terms of Material RemovalRate (MRR), KERF Width and Surface Roughness (Ra). In this project WEDM experiment using 0.25 mm diametercopper wire(Zinc coated) & EN-31 tool Steel work piece has been done for optimizing MRR, KERF width, Surfacefinish and reducing cost of manufacturing. By using multi objective optimization technique grey relational theory, theoptimal value is obtained for MRR, surface roughness and KERF width.
