In the present study, Optimization of EDM parameters has been studied during machining of Aluminium Alloy 7075. Four parameters namely peak current, pulse on time, duty cycle and flushing pressure are selected as input process parameters. Performance of EDM for Material removal rate (MRR), Surface Roughness (Ra) and Tool wear rate (TWR) is measured using a Copper electrode. Central composite design of Response Surface Methodology is opted for experimentation. The aim of the study is to find optimal levels of input process parameters to maximize MRR and to minimize the SR and TWR while finding ...

Central composite design of Response Surface Methodology is opted for experimentation. The aim of the study is to find optimal levels of input process parameters to maximize MRR and to minimize the SR and TWR while finding the most significant factors affecting the response parameters.
