Impact of Input Parameters on Material Removal Speed When PMEDM SKD11 Tool Steel

This paper introduces a study on optimizing the powder-mixed electrical discharge machining (PMEDM) for processing cylindrical shaped parts made of SKD11 steel to get the maximum material removal speed. In the study, an experiment was carried out with the use of the Taguchi method for experimental design and analyzing the results. Six input parameters, including the powder concentration, the powder size, the pulse on time, the pulse off time, the current, and the servo voltage, were selected to study the impact of the input factors on the MRS. In addition, optimal values of the input parameters to achieve maximum MRS have been proposed.
