Since the 1950s,industrial robots have been widely used in various fields,such as:transportation,packa-ging,devices,product testing,spraying and so on.Because the industrial robot is easy to operate,the device is conven-ient and the cost-performance ratio is high,so it can replace the NC machine tool in some cases,such as when the blank is soft and themachining precisionis low.Theindustrial robot usedin this paper is Yasukawa MOTOMAN-UP6 with an accuracy of 0.08mm.It uses NURBS curve and surface to finish the machining of complex surface,the method of the control process is introduced,and the accuracy of the method is verified.
