| Electrical discharge machining is a thermal erosion method that can be processed independently of the material's mechanical properties and the workpiece's geometry. Electrical discharge machining processing parameters directly affect the material's surface morphology and processing quality. This study investigated the effects of electrical discharge machining process parameters on the machining quality of AISI H13 hot work tool steel. Electrode material, pulse current and pulse on time were determined as factors for the experimental study. As a methodology, Taguchi L27 (3 × 3 × 3) full-factorial experimental design was used to optimise the effect of process parameters on surface roughness (Ra), processing time, crater diameter and material removal amount, which were identified as output parameters. The optimum factor levels were determined using Taguchi-based signal-to-noise ratio (S/N) criteria to optimise the output parameters. In addition, the analysis of variance results revealed that the pulse current was the most influential parameter for Ra, T and crater diameter. Conversely, the electrode material was the most noteworthy factor in material wear. The experimentation revealed that when the pulse current and pulse on time were increased, the processing time decreased, but the surface quality deteriorated. Moreover, linear and quadratic regression analyses were utilised to forecast the experiment's outcomes. The predicted and measured values exhibited excellent agreement. |
