Abstract:

This paper presents a study on modelling surface finish in Electrical Discharge Machining of tablet shape punches. In the study, experiments were conducted based on Box-Behnken design and the work-piece material was 9CrSi steel. A total of 27 experiments were done. The input parameters including current, pulse on time, pulse off time and voltage were selected. The influence of input parameters on the surface finish were investigated by analysing variance. In addition, based on the results of the experiments, a regression equation for determining the surface roughness is introduced. Also, the optimum input parameter values were found in order to get the minimum surface roughness.
