Optimization of machining parameters in electro chemical machining of Al5059/SiC/MoS2 composites using taguchi method

In this study, three different combinations of SiC were used by weight percentage and its particle size. The Molybdenum di sulphide also used with fixed weight percentage. Aluminium composite were manufactured by using stir casting method. Al5059 is reinforced with silicon carbide particles of 10, 20 & 40 μm size with 5%, 10% & 15% by weight and fixed amount of 2% Molybdenum disulphide has been used. Taguchi’s L27 orthogonal array is chosen to design the experiments and 27 test were conducted to study the effect of various machining parameters like applied voltage, feed rate, electrolyte concentration and percentage of reinforcement on the material removal rate (MRR), surface roughness (SR) are employed to find the optimal levels and to analyze the effect of electrochemical machining parameters on MRR, SR.
