With the continuous progress of aviation technology, higher requirements are put forward for the manufacturing process of key components of aeroengine. In this paper, the manufacturing process of key components of aero engine, such as turbine blades, turbine discs and combustion chambers, is discussed in depth, aiming to improve the performance and reliability of aero engine by optimizing and innovating the manufacturing process. The importance of manufacturing process of key components of aero engine is summarized in this paper. The working environment of key components of aeroengine is extremely harsh, and it needs to withstand extreme conditions such as high temperature, high pressure and high speed, so the performance of materials, the precision and stability of the manufacturing process are put forward extremely high requirements. The quality of manufacturing process directly affects the service life, economy and safety of aero engine. In this paper, the main manufacturing processes of key components of aero engine are analyzed in detail, including precision casting, precision forging, special machining, etc. Precision casting technology realizes the high precision forming of complex structural parts by controlling the temperature, pressure and other parameters in the casting process. The precision forging technology improves the mechanical properties and surface quality of the material by optimizing the forging process. Special processing technologies, such as EDM and laser processing, break through the limitations of traditional machining and realize the processing of difficult-to-process materials and high-precision parts. In terms of optimization and innovation of manufacturing process, this paper discusses the application of new materials and new technologies in the manufacture of key components of aeroengine. For example, advanced materials such as superalloy and titanium alloy are used to improve the high temperature and corrosion resistance of the components; The additive manufacturing technology is introduced to realize the integrated molding of complex structural components. Combined with simulation analysis and experimental verification, the manufacturing process parameters were optimized, and the machining accuracy and consistency of the components were improved. This paper summarizes the development trend of manufacturing process of key components of aero engine. In the future, with the continuous development of aviation technology, higher requirements will be put forward for the manufacturing process of key components of aviation engines. The manufacturing process will pay more attention to interdisciplinary integration, introduce more new materials, new technologies and intelligent manufacturing concepts, and promote the development of aero-engine manufacturing to a higher level. At the same time, the intelligent and digital manufacturing process will also become an important trend, through the introduction of intelligent equipment, Internet of Things technology and other means to achieve real-time monitoring and intelligent control of the production process, improve production efficiency and product quality.
