Abstract

Aluminium composites are tough to machine by using conventional method. In order to increase machinability of aluminium-based composite a non-conventional method of machining has been used. Electrical Discharge Machining (EDM) is one of the kind of machining process which has often uses for machining of aluminium composites. The objective of this chapter is to determine the ideal setting of the process parameters on the electrical discharge machining while machining Aluminium-Rice Husk Ash (LM25-RHA) composites in which three different variation (4%, 8%, 12%) of Rice Husk Ash has been used. The parameters considered are pulse current (Ip), gap voltage (V) and pulse-on-time (Ton); whereas its effect are analysed on Electrode Wear Rate (EWR), Material Removal Rate (MRR) and Surface Roughness (Ra). The optimal setting of the parameters are determined through experiments planned, conducted and analysed using the Taguchi method.
