A review on influence of electrical process parameters in EDM process

Since the thermal energy produced in electrical discharge machining process is due to the applied electrical energy, it is very important to enhance the electrical process parameters to improve the process efficiency. The present study discusses about having an overview of the EDM process, modeling of process parameters, and influence of process parameters such as input electrical variables, pulse shape, and discharge energy on performance measures such as material removal rate, surface roughness and electrode wear rate. This study also discusses about controlling the electrical process parameters, and empirical relationships between process parameters and optimization of process parameters in EDM process. From the review results, it has been observed that the efficacy of the machining process can be improved by electrical process parameters, and only less attention has been given for enhancing such parameters.
