This article presents the results of a study on optimization of electrical discharge machining (EDM) when machining SS304 stainless steel cylindrical shaped parts. The objective function of the problem is the maximum material removal speed (MRS). An experiment has been designed and performed to solve this problem. In addition, the experimental design and result's analysis were carried out by applying the Taguchi method with the support of the Minitab R19 software. Besides, the influence of the input process parameters, including the pulse on time, the pulse off time, the servo current, and the servo voltage on the MRS was explored. Furthermore, the optimal inputs of the EDM process factors to achieve the maximum MRS have been proposed.
