In this paper Aluminium & Silicon powders mixing into the dielectric fluid of EDM on machining characteristic of various materials has been studied. Various process parameters namely peak current, pulse-on time, pulse-off time, powder concentration, powder grain size and nozzle flushing, duty factor, etc have been considered. The process performance is measured in terms of Response variables like Material Removal Rate(MRR),Surface Finish(SF) / Surface Roughness(SR),Tool Wear Rate(TWR)/Electrode Wear Rate(EWR),etc. Various types of dielectric fluids are used. Optimisation Methods used are Taguchi Method, Response Surface Methodology, etc. This paper reviews the research work carried out from the inception to the development of Aluminium & Silicon Powder Mixed Dielectric electric Discharge Machining within the past decade & also briefly describing the Current Researches conducted & optimization Technique used in the Aluminium & Silicon Powder mix Electric Discharge Machining(PMEDM) field.
