Abstract
In electrical discharge machining (EDM) powder material can be mixed into the dielectric fluid to improve quality of machining surface of components. Therefore, finding suitable input parameters of this process becomes an important task. This paper presents a methodology to find the optimum input factors of the EDM process when adding nanosilicon carbide powder into the dielectric fluid for processing cylindrical shaped parts. In this research, the Taguchi method was used for experiment design in order to investigate the effect of the input parameters on the surface roughness. Also, optimum input factors for minimum surface roughness (RS) was proposed. The result from the deviation of SRbetween the analysis and the experiment demonstrates that the optimum input parameters are helpful to predict the value of surface roughness. Therefore, this can increase the economic and technical effectiveness in EDM process.
