In this investigation, nanocomposites combined with silicon carbide and graphite are made using casting method. T6 heat treatment is applied to nanocomposites to improve their mechanical properties. The material is machined using an electrical discharge method. To determine effectiveness of electrical discharge machining (EDM) method the material removal rate (MRR), tool wear rate (TWR), and surface roughness (SR) are all measured. It has been found that copper is the best material for EDM process. The L27 Taguchi technique is used to complete the experimental trails. The signal-to-noise (S/N) ratio is used to calculate the optimal machining parameters, such as MRR, TWR, and SR.
