This paper investigates the effect of electrical discharge machining parameters on the surface roughness as an alternative method for machining of Al/SiCp metal matrix composites produced with the powder metallurgy. Current, electrode type, pulse-on-time, particle reinforcement weight ratio and voltage were used as the process parameters. An experimental plan (L-18) was constituted by using the Taguchi orthogonal design. Results of experiments showed that pulse-on-time (34%) and current (31.26%) is the most influencing parameters. Besides this, the percentage contribution of particle reinforcement on the surface roughness is 6.71%. DOI: 10.12693/APhysPolA.123.421
