Abstract
In EDM, especially in small holes EDM machining, there will be a lot of debris produced which is difficult to remove from narrow gap. If the debris can’t be removed in time, it will affect the machining accuracy and efficiency, and sometimes even unable to complete the processing. In this paper, the debris movement and escaping process in gap flow between electrodes in the case of Ti alloy small hole EDM machining were studied by combining the means of simulation analysis and experiment study. The perturbation generated by the movement of self-adaptive tool in the gap flow were taken into consideration and the methods of smoothing and remeshing were also applied in order to build a model for the debris movement in the gap flow. And then, the law of debris movement under different depths was analyzed and the distribution rules about pressure field and velocity vector were summarized. Finally, the model was verified by the experiment result showing that the appearances of uneven wear at the bottom of hole and the taper wall are both in accordance with simulating conclusions.
