Abstract: Wire Electrical Discharge Machining (WEDM) is a specialized thermal machining process capable of accurately machining parts of hard materials with complex shapes. Machine tool industry has made exponential growth in its manufacturing capabilities in last decade but still, machine tools are not utilized to their full potential. In the present work, an attempt has been made to optimize the machining parameters in WEDM of aluminium silicon nitride (Al-10%Si3N4) for surface finish, accuracy and electrode wear based on (L27 Orthogonal Array) Taguchi technique. Experiments were carried out under varying pulse-on-time, pulse-off-time, current and bed speed. An orthogonal array, the signal-to-noise (S/N) ratio and the analysis of variance (ANOVA) were employed to study the response variables in the WEDM of Al-10%Si3N4 metal matrix composite material. To validate the study, confirmation experiment has been carried out at the optimum set of parameters and it was concluded that optimized parameters have shown good results, so these parameters can be used to achieve good surface finish, accuracy and to minimize electrode wear than before.
