As the leader of aeroengine manufacturing industry, it is a highly complex and precise thermal machinery. Each manufacturing method is extremely demanding and requires a large amount of materials. The high-temperature parts not only need to withstand high temperature, but also need to withstand strong air pressure. Small errors directly lead to the failure of the whole aircraft. At present, the design and manufacture of aeroengines are very complex, covering tens of thousands to hundreds of thousands of small parts. A large number of non-metallic special coatings such as titanium alloy, high-temperature gold and stainless steel are used. These materials not only have high hardness and brittleness, but also have high melting point and low thermal conductivity. For example, the interior of turbine blades not only has special shapes, It also has high temperature resistance. If the traditional processing method is adopted, not only the operation is complex, but also the process requirements are difficult to meet. Therefore, it is necessary to combine the current high-tech means - laser cutting machine with laser technology.
Now, with the development of science and technology and related industries, laser industrial technology is more and more widely used in the field of aerospace. As an important technology of laser application, laser cutting technology has been widely used in the field of aerospace, especially in the field of aeroengine.
