Manufacturing of the better quality ceramic products with more accuracy and precision is a great challenge in the current industrial field. Electrically non-conducting materials like ceramics, composites, alumina, glass etc can be machined easily using Electrochemical Discharge Machining (ECDM) process. The performance characteristics of ECDM process e.g. material removal rate (MRR), machining depth rate (MDR), radial overcut (ROC) and heat affected zone (HAZ) are influenced by various process parameters such as applied voltage, inter-electrode gap, temperature, concentration of the electrolyte, type of electrolyte, shape, size and material of the electrode and also the nature of the power supply etc. This paper presents the optimization of m-EDMing of Silicon Nitride by utilizing Multi-Objective Optimization by Ratio Analysis (MOORA). Also, a multi choice decision analysis i.e. Analytic Hierarchy Process (AHP) is applied for optimization.Keywords

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.Keywords
