摘要: 为研究椭圆振动车削表面三维几何形貌形成规律及影响因素,采用金属切削理论对椭圆振动切削过程和三维切削模型进行了分析。研究结果发现:切削过程中相邻两转之间不同的相位差特征值对最终表面形貌有着重要的影响;通过已有的试验结果表明,相位差特征值分别为0和0.5时所形成的表面形貌截然不同,与理论分析结果相吻合。

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
