摘要：
To solve the problems of the poor machining performance, low processing quality and poor efficiency of titanium alloys commonly used in aerospace, a new processing technology, high-speed ultrasonic elliptical vibration milling process is proposed. It is an ultrasonic intermittent cutting method in which the tip of the blade moves in an elliptical path in the plane, which can effectively improve the quality of milling and break through the limitations of the conventional ultrasonic vibration processing on the critical speed. High-speed ultrasonic vibration milling process is introduced into the common thin-walled parts structure, web processing. The principle of microscopic separation of the process is analyzed first, and the experiment is designed to verify its effect in the processing of titanium alloy webs. The results show that the high-speed ultrasonic vibration milling process has a stable increase in both the number of cutters and the surface roughness value in the processed surface compared to the ordinary milling processing method. The roughness reduction is about 10% to 40%, and the relieving amount reduction is about 50%. © 2019 Journal of Mechanical Engineering.
