This paper presents a study on modelling surface finish in Wire Electrical Discharge Machining of 9CrSi tool steel. In the study, experiments were conducted based on full factorial design and the work-piece material was 9CrSi steel. A total of 32 experiments were conducted. The input parameters including cutting voltage, pulse on time, pulse off time,servervoltage, wire feed and cutting speed were selected. The effect of input parameters on the surface roughness were investigated by analysing variance. Furthermore, based on the results of the experiments, a regression equation for determining the surface roughness is proposed.
