Abstract
This article presents a study on the investigation of the effects of the input parameters on the cutting speed in machining 90CrSi tool steel using wire cut electrical discharge machining (EDM). In this work, experiments were performed with factorial design with a total of 32 experimental runs. In addition, the input factors including the pulse on time, the pulse off time, the cutting voltage, the server voltage, the wire feed and the feed speed were carefully selected for the investigation. The effects of this factors on the cutting speed were learned by analysing variance. Moreover, a regression equation to determine the cutting speed was introduced.
