An Investigation into Improving Worn Electrode Reliability in the Electrical Discharge Machining Process

In this paper, the use of a strength–stress interference model to study electrode reliability during wear in electrical discharge machining has been reported. In order to improve the electrode reliability, the Taguchi method, which is a powerful tool for parameter design of performance characteristics is used to determine machining parameters for minimum electrode wear ratio in electrical discharge machining operations. Through this study, not only is the electrode reliability improved, but also the machining parameters that significantly affect the electrode wear ratio in electrical discharge machining operations are obtained. Experimental results are provided to verify this approach.
