Description 52-61
Travelling wire electrochemical spark machining (TW-ECSM) is newly evolved and developed hybrid machining
process for the machining of advanced non-conducting materials which possess significant values of the properties like high
strength, high wear and fatigue resistance, high refractoriness and high strength to weight ratio, etc. The control parameters
like voltage, wire feed rate, electrolyte concentration and inter-electrode gap were selected as Input Parameters and Material
Removal Rate (MRR), and Surface Roughness (SR) were the corresponding output responses. In present work, for multiobjective
optimization and purpose of better control of machining parameters, three approaches, grey-relational analysisprincipal
component analysis (GRA-PCA), fuzzy logic and desirability function approach are used to determine the optimal
combination of TW-ECSM process variables. Results of fuzzy logic and GRA-PCA approach are found comparable while
desirability function approach is found to be capable of predicting the optimal responses at such levels of process variables
also at which experiments are not performed. Consequences of the applied approach in the present work are also validated
by conducting the confirmatory experiments and results are found in well agreement with the predicted results.
