Aviation bearing bracket is an important part of aircraft and other aviation products. In this paper, based on additive and subtractive hybrid manufacturing technology with high manufacturing flexibility and high machining accuracy, a machining scheme of aviation bearing bracket is designed. First, milling simulation was carried out to obtain the influence law of different cutting parameters on machining deformation, so as to guide the selection of reasonable finish machining parameters in the subsequent process planning. Then, the temperature field distribution of workpiece in the additive manufacturing was simulated, and the influence of different additive manufacturing parameters on the results was analyzed to determine the parameter selection range. Finally, considering the material utilization rate, machining accuracy, machining efficiency and machinability in the machining process of aviation bearing bracket, and proceeding from additive, subtractive and alternating manufacturing methods, the manufacturing process arrangement and process planning for aviation bearing bracket were designed.
