Abstract: In order to find the influence factors and the influence law of the 3-D micro-surface formation of ultrasonic elliptical vibration cutting, the elliptical vibration cutting process and 3-D cutting model are analyzed based on the metal cutting theory. The results show that the different phase difference eigenvalue between two adjacent turns in vibration cutting process has an important influence on the final surface geometry. The existing cutting test results show that the final surface shapes with the eigenvalues of 0 and 0.5 are very different, and the results agree with the theoretically analyzed results. Key
