Abstract It is submitted that new approach is tried to find out what would be the outcome if Aluminum 2618 reinforced by AlN (Aluminum Nitride), Si3N4(Silicon Nitride) & ZrB2(Zirconium Boride) particles were fabricated in Wt % (x = 0,2,4,6,8) by stir casting method. If the wt% is increased, the mechanical properties of the composite will proportionally increase. There will be no other promising technique than Electrical Discharge Machining (EDM) for machining metal matrix composites when they were conducted on the Aluminum 2618 composite work piece using a copper electrode in an EDM machining. It becomes very vital in the field machines and mechanism to find out Current(I), Pulse on time(TON), Pulse off time (TOFF) on Metal Removal Rate (MRR),Tool Wear Rate(TWR) on the machining of hybrid Al2618 metal matrix composites. Taghuchi's design of experiment was used to analyse the machining characteristics of hybrid composites. To effect the parameters like current (I), Pulse on time(TON), Pulse off time (TOFF) has been chosen as the input parameters of this work. Machining results go to show that Al2618 composites have improved mechanical properties and as a result of Material Removal Rate (MRR) and Tool Wear Rate (TWR) are reduced. Hence ANOVA (Analysis of Variance) and signal to Noise ratio are used to determine the influence of input parameters on the Material Removal Rate and Tool Wear Rate (TWR). © 2015 Elsevier B.V.
