【Abstract】 Due to the limitation of the small and medium-modulus internal gear structure, it is difficult to use the traditional grinding process for the tooth profile processing after the tooth surface is hardened. Therefore, an EDM forming milling method was proposed. Due to the electrode rotation discharge, the electrode discharge area was large. The processing accuracy was less affected by electrode loss, and the products of electro-corrosion were better discharged. The processing device was designed according to the processing principle and method, and the basic process law was studied by single factor experiment. According to the results of the single factor experiment, a representative level was selected to design an orthogonal experiment, and the optimal machining conditions were studied through orthogonal experiments combined with surface roughness and machining efficiency. A comparative test was designed. The experimental results show that compared with the traditional EDM processing method, both the surface quality and processing efficiency of the workpiece are significantly improved.更多还原
