摘要:
针对机器人铣削过程中因刚度不足导致的铣削力过大,进而引起机器人加工精度低的问题,该文提出了一种基于旋转超声的机器人铣削加工方法。基于KUKA工业机器人开展机器人旋转超声铣削和普通铣削对比实验,探究旋转超声加工与工业机器人结合的可行性。分析了超声振动对铣削力、颤振和表面精度的影响规律。实验结果表明,超声振动可使铣削力降低22%,且颤振振幅降低25%以上,同时高频的振动冲击可有效抑制颤振,改善表面质量。
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.
