Abstract

This paper introduces a study on the influence of process parameters on the machining time in Wire Electrical Discharge Machining of 9CrSi tool steel. In this study, a total of experiments were performed based on full factorial design and the work-piece material was 9CrSi steel. The input parameters including cutting voltage, pulse on time, pulse off time,servervoltage, wire feed and cutting speed were selected for investigation of the effects of the input parameters on the machining time. The influence of the 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 machining time wasproposed.

Keywords

WEDM, machining time, full factorial design, tool steel machining.
