The particularity of the use of aerospace products determines the special requirements for the materials used by aerospace parts. Nowadays, stainless steel, high strength steel, composite material, aluminum alloy, titanium alloy and superalloy have been widely used in aerospace industry, with large processing difficulty and deep cavity, deep hole and complex structure. The weak rigid parts such as hybrid surfaces, such as poor accessibility, are more complex, and the performance is more and more demanding on the surface integrity and reliability. It has an urgent need for high performance tools with long life and high reliability. The gradual application of new materials, new structures and new technologies in the processing of Aeronautics and Astronautics has caused more and more difficulty in the processing of Aeronautics and Astronautics. In turn, it is necessary to use high performance standard cutters and special tools in aerospace parts processing to meet the increasing processing requirements and to the tool life. Consistency and reliability are highly demanded.

With the mutual promotion of the material, the tool material and the structure of the tool, the aerospace manufacturing industry is developing continuously. It can be said that the continuous development of the tool is the driving force of the continuous development of aerospace manufacturing industry. At present, the tools of aerospace manufacturing are mainly used for the forming of products. The widely used tool materials are as follows: tool steel (carbon tool steel, alloy tool steel, high speed steel), hard alloy, ceramics and super hard tool materials. Among them, cemented carbide cutting tools account for the largest proportion, and they are the leading tools in aviation manufacturing. Compared with cemented carbide, ceramic and super hard tool materials have higher hardness, thermal hardness and wear resistance, and the chemical stability and antioxidant capacity are better than hard alloys. Therefore, ceramics and super hard tools have gradually become the mainstream in the development of aerospace industry.
