Abstract

This paper shows a study on the influences of the process parameters of wire cut electrical discharge machining (WEDM) on the surface roughness in machining 90CrSi tool steel. For this investigation, an experiment was designed and performed. In addition, 6 input parameters including the pulse on time, the pulse off time, the cutting voltage, the server voltage, the wire feed and the feed speed were carefully chosen for the work. The effects of these factors on the surface roughness were evaluated by analysing variance. Moreover, a regression equation was proposed for determining the surface roughness.

Keywords: WEDM, wire-cut EDM, cutting speed, factorial design, tool steel machining
