Abstract

Abstract: Aluminium 7075 finds its application as structural material in sectors such as automotive, transport and aeronautical. This paper work deals with the machining of Aluminium 7075 with brass electrode using Electrical Discharge Machining Process. The effect of EDM process parameters on the various output of work piece were statistically examined with series of runs. L27 set of experiments are performed with four inputs (Peak Current, Voltage Gap, Pulse ON Time and Flushing Pressure) and their three levels. By setting the required parameters, Material Removal Rate (MRR) is estimated. The results show that MRR is essentially impacted by peak current, voltage gap and pulse on time. Whereas, the effect of flushing pressure on MRR is insignificant. Diagnostics Curves for the output were obtained. ANN models are developed considering three distinguish hidden layers (8, 9 and 10).
