IIn the stage of civil aviation engine research, the design state iteration is fast, the characteristic parameters are many, and the structure of the measuring part is complex. As an important geometric measurement tool, engineering coordinate measurement results are often used as an important basis for product design change/airworthiness manufacturing compliance review. However, the lack of measurement ability, the inconsistency of measurement results and the long training cycle of measurement engineers greatly restrict the development progress of the product. In this paper, engineering CMM management of manufacturing process is proposed: According to the CMM requirements of aero-engine engineering in the scientific research stage, the key measurement items are decomposed, the measurement comparison method is introduced, the measurement comparison assessment mechanism is established, the ability of engineering CMM personnel in manufacturing process is controlled and evaluated, and the purpose of rapidly improving the measurement level of personnel is realized. In addition, establish the physical verification, accounting and change mechanism of the measurement program, decompose the same family measurement process, improve the reliability of the measurement program on the basis of measurement efficiency, and ensure the measurement quality of the engineering three coordinates. Since the operation of the system, the measurement problems of field measurement personnel have been significantly reduced, and the consistency of measurement results has been improved, which has the practical conditions for further popularization and application to the manufacturing process of aero engine supply chain.
