(BQ) 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. | archives of civil and mechanical engineering 15 (2015) 87–94 Available online at ScienceDirect journal homepage: Review A review on influence of electrical process parameters in EDM process T. Muthuramalingam a,*, B. Mohan b a b Department of Mechatronics Engineering, SRM University, Kattankulathur, India Department of Mechanical Engineering, CEG Campus, Anna University, Chennai, India article info abstract Article history: Since the thermal energy produced in electrical discharge machining process is due to the Received 12 July 2013 applied electrical energy, it is very important to enhance the electrical process parameters to Accepted 16 February 2014 improve the process efficiency. The present study discusses about having an overview of the Available online 14 April 2014 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 Keywords: as material removal rate, surface roughness and electrode wear rate. This study also EDM discusses about controlling the electrical process parameters, and empirical relationships EWR between process parameters and optimization of process parameters in EDM process. From Discharge the review results, it has been observed that the efficacy of the machining process can be MRR improved by electrical process parameters, and only less attention has been given for Surface enhancing such parameters. # 2014 Politechnika Wrocławska.

Introduction Electrical discharge machining (EDM), otherwise known as thermal erosion process, is one of the non-conventional machining processes, where tool and workpiece do not come into contact with each other during the machining process. The progression of events constituting the process of material erosion from the work surfaces .
