In this paper, the tool wear prediction model is established and the model theory is combined with the actual production in the field. The machining parameters that maximize the economic benefits of the difficult-to-machine materials (GH2132) are given under the premise of ensuring the quality of the machining. The verification of engine blade profile machining and the optimal combination of machining quality, machining efficiency and machining cost have provided an important basis and solution to the problem of optimizing the cutting parameters of aviation typical difficult-to-process materials, which is very hard to improve aero-engine Processing of materials processing efficiency and reduce processing costs is of great significance.
