Parametric Analysis of Travelling Wire Electrochemical Discharge Machining Process

Travelling Wire Electrochemical Discharge Machining (TW-ECDM) process is a special type of Electrochemical Spark Machining (ECSM) process which has a greater effectiveness for machining of electrically non-conducting material like hylam based fiber reinforced plastics (FRP). The recent research paper focuses the parametric analysis on machining criteria such as material removal rate (MRR) and Overcut (OC) for slot cutting operation considering applied voltage, electrolyte concentration, feed rate of wire and pulse on time etc as process parameters. This paper shows the single and multi-objective optimization for determining the optimal parametric combination of TWECDM for maximum MRR and minimum OC based on response surface methodology (RSM). From the parametric analyses it is concluded that applied voltage has more significant effects on MRR and OC during TW-ECDM slot cutting operation.
