Relationship between the Fine Discharge Parameters and Craters EDMed of the NAK80 Steel

摘要：

The crater diameter and depth of the surface machined by electrical discharge machining (EDM) were used to evaluate indexes for EDMed surface．The influence of discharge parameters selected on the crater diameter and depth in mirrorlike surface EDM process was investigated．and the optimization scheme was obtained．An L16(44x23) Taguchi standard orthogonal array was chosen for the design of experiments．Experimental results indicate that peak current and open discharge voltage have more lnfluence on the crater diameter and depth in comparison with pulse off-time and pulse duration．Also the results confirm that the crater depth iS about 10 to 20 percent of its diameter while the near-mirror EDM conducted in the NAK80 steel with fine discharge parameters．
