This paper deals with the influence of the EDM process parameters on the surface roughness of AlNiCo alloys. A BP 93L machine with an electronic generator was used to perform the machining. The workpiece was made of an AlNiCo alloy. Kerosene was used as a dielectric. During the EDM process, the parameters of current were changed. The impulse time and break time were also changed. The surface roughness and a 3D surface profile were measured. Roughness measurement was carried out using a Talysurf CCI Lite non contact 3D surface profiler. The analysis of the results was carried out with the Statistica 10 program.Keywords: Electrical discharge machining (EDM), AlNiCo alloys, suface roughness, 3D surface profile
