The Kinematics Research of Elliptical Vibration Polishing Based on the Vibration Parameter Optimization

Abstract:

Polishing, the last manufacturing procedure in the process of optics manufacturing, has been restricted by the existed contradictory propositions of efficiency and accuracy. As a result, a variety of new combined processing techniques put forward by researchers in many countries. While, elliptical vibration polishing (short as EVP) well considers efficiency and accuracy in machining. This paper focuses on the kinematics research of EVP tools, and proves the superiority of EVP through the vibration parameter optimization. Perfect tool path gets by the impact analysis of phase difference, frequency ratio and amplitude of the polishing tool. Meanwhile the optimum frequency for EVP is studied from the cost and efficiency perspective. The simulations reveal that the perfect tool path will be obtained in the following situations: phase difference at 90°, frequency ratio at 0.909, adjusts the tool vibration amplitude in consideration of minimum curvature radius in polishing area, and appropriately select the vibration frequency.
