Abstract :

This paper presents an investigation of WEDM process using Zinc coated brass wire as electrode on EN 8. WEDM is a thermal machining process that utilizes spark discharges to erode a conductive material. Optimum machining conditions were obtained with maximum cutting speed and minimum surface roughness as objective. It was observed that with increase in peak current, cutting speed and surface roughness increases. Response surface methodologies D optimality test was used to determine the optimal machining parameters, among which the peak current for cutting speed and the gap voltage for surface roughness were found to be the most significant. The obtained optimal machining conditions are peak current of 190 A, voltage of 15 V, Pulse on time of 112.62 µs, Pulse off time of 60 µs and Wire tension of 6 N which is validated by confirmation test.
