Abstract:
Aiming at the low machining precision caused by large milling force due to the low rigidity in the process of robot milling,the robot machining method based on rotating ultrasonic is proposed here. In order to explore the possibility of the rotating ultrasonic machining combined with the industrial robots,the robotic rotating ultrasonic milling(RRUM)experiments and the robotic conventional milling(RCM)experiments are set up based on KUKA industrial robots. The effects of ultrasonic on milling force,chatter and surface precision are analyzed respectively. The experimental results show that the ultrasonic vibration can reduce the milling force by 22% and the flutter amplitude by more than 25%. Meanwhile,high frequency vibration can effectively suppress flutter and improve the surface quality.
