چکیده :

The electrical discharge machining process is one of the most important and suitable processes for machining of hard and brittle metals such as superalloys. This process, which is part of the thermoelectrical machining process, is capable of machining complex geometries on metals. In this research, using Taguchi method and variance analysis (ANOVA), the output parameters of EDM process on Inconel 690 superalloy have been optimized. Input factors in this study include discharge current, pulse duration, gap voltage and duty factor as well as output factors of the process, including the material removal rate, surface roughness and surface microstructure. First, using the Taguchi method, the optimal arranging of the experiment was determined and then by performing the experiments and analysis of the variance, the contribution of each input parameter to the output response of the process was determined and finally the optimal input parameters were introduced. Also, the result of the optimization of the output factors of the process, including maximum material removal rate, minimum surface roughness and suitable microstructure with minimum surface cracking.
