In order to achieve uniform surface finishing of aero-engine blades and improve the performance of aeroengine compressor blades, the influence of container configuration and blade installation attitude on polishing effect was studied based on discrete element numerical simulation. The results show that within the range of experimental parameters, when the container height is 124 mm, the container width is 120 mm, the container length is 80 mm, and the blade surface is installed at 90° with the vibration direction, the wear depth and uniformity of the compressor blade finishing are better, which is the optimal container configuration size and installation attitude parameters. After finishing the compressor blade according to the optimal parameters obtained from the simulation, the surface burr and forged oxide of the compressor blade were removed; The sharp edge is passivated, the edge is rounded and neat; The surface is bright. The roughness grade of the blade surface is greatly improved, and the key dimensions of the blade are within the allowable range. The stress state is improved. The research method and results lay a foundation for the efficient and low-cost processing of compressor blades.
