ABSTRACT
Electric Discharge Machining (EDM) is widely accepted process to machine hard materials such as composites and alloys being used in various industrial applications. Various methods have been employed so far to improve its performance measures such as Material Removal Rate (MRR), Tool Wear Rate (TWR) and Surface Roughness (SR).The purpose of present study is to investigate the effects of various process parameters such as peak current, pulse on time, pulse off time, speed of rotation of tool and flushing pressure on performance measures such as MRR, TWR and SR.. Taguchi method has been adopted to design the experimental plan. For the conduction of experiments L18 orthogonal array was used. It is found that peak current, pulse on time and pulse off time contribute significantly, whereas speed of rotation of tool and flushing pressure contribute least to improve performance measures. For results and analysis MINITAB 17 software is used.
