Technical Field

[0002] In the aviation field, the manufacturing accuracy and surface quality of parts are directly related to the safety, reliability and performance of aircraft. With the rapid development of aviation technology, more and more stringent requirements are put forward for the manufacturing process of aviation parts. Grinding is a key link in the manufacturing process of aviation parts. Its quality directly affects the fatigue strength, corrosion resistance and overall service life of parts. Traditional grinding methods, such as manual grinding, are not only inefficient, but also difficult to ensure the consistency of grinding quality. Problems such as uneven grinding, over-grinding or under-grinding are prone to occur. At the same time, the shapes and structures of aviation parts are becoming increasingly complex, and manual grinding is difficult to meet the grinding needs of high-precision and complex surfaces. If the workpiece material is not determined during the grinding process, the set grinding steps are performed, which will make it difficult to ensure the surface accuracy of the workpiece after grinding, affecting the reliability and service life of aviation parts under complex working conditions. In addition, if the grinding tool does not match the workpiece material, the service life of the grinding tool will be shortened due to excessive wear, increasing the replacement frequency and cost.
