In this research, discharge duration and pulse frequency were studied to determine the optimum conditions for creating a single crater. In addition, the relationships between pulse frequency and the surface characteristics of a whirling electrical discharge texturing (WEDT) processed were determined. It was confirmed that the texture-area ratio and the total removal volume of craters, but not crater diameter or crater depth, can be controlled by adjusting pulse frequency. Moreover, after
