Abstract: Aluminum and its alloys such as Al6061 have many characteristics like low density, high electrical and thermal conductivity, and resistance to corrosion. The addition of cerium to some alloys led to improve the structure and mechanical properties of alloys. Through the thermal erosion process of Electrical Discharge Machining (EDM), an electrically-produced spark vaporizes materials that are electrically conductive. This paper examines the viability of improvement of material removal rate in electric discharge machining of AL6061-%0.5Ce. For the purpose of this research, a copper electrode with a 500μm diameter was utilized. The performance measures of the machining process were investigated regarding the material removal rate (MRR). Current, pulse on time, and polarity were the process parameters. Findings showed that current and pulse on time are significant parameters.
