Аннотация: In order to improve the machining characteristics of electrical discharge machining of deep micro-holes, rotational electrodes have been widely used. This paper is devoted to the theoretical and experimental investigation of the process of evacuation of debris particles from the interelectrode gap during electrical discharge machining of deep micro-holes. Mathematical modeling of hydrodynamic processes in the interelectrode gap is carried out on the basis of numerical solution of the equations of motion of incompressible viscous fluid, which allows one to estimate the influence of the shape and size of the tool-electrodes and their rotation on the evacuation of debris particles from the interelectrode gap. It was found that the use of tool-electrodes with a non-circular cross section enables one to accelerate the evacuation of debris particles. An experimental study of the process of electrical discharge machining of deep micro-holes is performed, and the simulated results are compared with the experimental data.
