Abstract

This study investigates the influence of voltage U, current intensity I, and pulse duration Ton on the material removal rate MRR in electrical discharge machining (EDM) on C45 steel. The work uses the Taguchi optimization methodology with three input parameters (voltage U, current intensity I, pulse duration T on), and each parameter set at three levels, resulting in a total of 9 experiments to evaluate the MRR for optimal efficiency. The results indicate that the material removal rate reaches the highest efficiency at 0.355 g/min with the most optimal set of parameters (U = 30V, I = 1.5A, Ton = 80μs). This study serves as a foundation for optimizing parameters to achieve the highest material removal rate in EDM processing.
