Wire electrical discharge machining (WEDM) belongs to the advanced technology widely used in the engineering industry. In WEDM process material is removed from workpiece by series of electrical sparks. The article studies the interactions between process parameters and the final quality of the generated surface (for steel 1.2201). The influence of WEDM parameters: initial current Iw (A), initial pulse time tw (µs), discharge duration ton (µs), on the surface roughness were experimentally evaluated. The obtained results show that surface roughness Ra after WEDM process for the first cut is the range between 1.9 – 2.5 µm. The primary factor in determining the treatment process is the energy of electrical discharge. The effect of the WEDM parameters on the functional parameters of surface roughness: Sk - roughness of the core, Spk roughness of the peak, Svk - roughness of the valleys are also presented and discussed.Keywords: Wire Electrical Discharge Machining, surface texture
