超声振动辅助微细铣削工件动态位移分析
Dynamic displacement analysis on ultrasonic vibration assisted micro-milling workpiece
摘要
Abstract
In order to explore new way for improving the micro-milling condition and enhancing the micro-milling accuracy, the influence of ultrasonic vibration assisted micro-milling on the dynamic change of workpiece was investigated. The waveform characteristics of main cutting force for both common milling and ultrasonic vibration assisted micro-milling were calculated and analyzed. A tool-workpiece vibration system model was established, and the dynamic displacement of workpiece before and after imposing ultrasonic vibration was theoretically calculated. The milling groove test with taking 2A12 as experimental material was performed for verification. The theoretical analysis and experimental results show that the ultrasonic vibration assisted micro-milling in feed direction can obtain the pulse-like cutting force, attain the uniform and small chips, reduce the dynamic change of workpiece during milling, and improve the dimensional accuracy of milling at the same time.关键词
