摘要：
It is easy to generate burr on the edge of holes when industrial robot drills the aluminum alloy stacked component. The assembly accuracy and efficiency of aircraft are severely affected. Aimed at the problem of robotic low stiffness, a model is developed to compute the burr height of holes produced by robotic rotary ultrasonic drilling. First, the impact of high frequency vibration on the burr height is invesgated by drilling experiments. Then, the empirical formula of drilling force in robotic rotary ultrasonic drilling aluminum alloy stacked component is obtained by analysing the experimental results. Furthermore, based on the classical thin plate bending theory and energy method, the influence mechanism of ultrasonic vibration and drilling position rigidity on the burr height of drilling is clarified. Finally, verification experiments are carried out and the results show that this method has high calculation accuracy and the relative error is within 13%. © 2020, Editorial Board of JBUAA.
