摘要
针对机器人钻削(RCD)CFRP/铝合金叠层材料中钻削力过大引起柔性机器人姿态变形、影响制孔精度与质量的问题,提出了一种机器人旋转超声钻削方法(RRUD),实现钻削力的减小。实验结果显示:加入旋转超声后机器人钻削力显著减小,麻花钻与机器人旋转超声加工系统的匹配性优于三尖钻。采用小进给、高转速的工艺参数可以进一步减小机器人钻削力。为机器人旋转超声钻削CFRP/铝合金叠层材料的钻削力优化提供了参考与依据。
The robot often produces too large cutting force in the process of robot common drilling（RCD） CFRP（CCF300）/Al（7075） aerial laminated material, which result in the flexible robot posture deformation and effect of the quality of hole accuracy and problems. The method of robotic rotary ultrasonic drilling（RRUD） for was put forward to study the reduction of drilling force. The experimental results show that the drilling force of the robot is reduced with joining of rotary ultrasonic. The matching between the twist drill and the robot rotary ultrasonic machining system is better than the three point drill. The process parameters of small feed and high speed can further reduce the drilling force of the robot. The conclusions provide reference.
