Description

technical field

[0001] The invention relates to the technical field of cutting difficult-to-machine materials and ultra-precision cutting, in particular to a three-dimensional elliptical vibration cutting device for space curved beams. Background technique

[0002] With the rapid development of science and technology, difficult-to-machine materials such as hardened steel and silicon carbide have attracted more and more attention. However, the processing performance of the above-mentioned materials is poor by traditional cutting methods, which will lead to severe diamond tool wear, deterioration of machined surface quality and reduced machining accuracy during the cutting process. In order to solve the above problems and make precision machining more widely used in military, aerospace and civilian industries, academic researchers have proposed a series of solutions, such as low temperature cutting, carbon saturation cutting and elliptical vibration cutting. Among them, ellip...
