Optimisation of WEDM Parameters Using Taguchi Method and Fuzzy Logic Technique for Al-6351

WEDM is a non-conventional machining process, there is no physical contact between the electrode and the work-piece to be cut. As the charged wire makes no physical contact with the work-piece in EDM machining hence no cutting force is involved (S.G. & B.M., 2015) and eradicated all kinds of stress, vibration and chatter problems (Joshi, 2011). The highly accurate and precise machining parts are not possible through traditional machining. Nowadays, WEDM is widely used in production of complex shaped components used in different industries such as aerospace, automobile and other industrial application ( Dongguan Lemo Precision Metal Products Co.,Ltd, 2002)
