[0002] Aircraft engine rings are an indispensable key component of aircraft engines. These annular parts play an important role in the structure and function of aircraft engines. They are usually made of difficult-to-deform metal materials such as high-temperature alloys, titanium alloys, and aluminum alloys to adapt to extreme working conditions such as high temperature, high pressure, and highly corrosive environments. In the process of ring production, close trimming processing is required.
