Research on Robotic Polishing of Optic Aspheric Component

计算机控制光学表面成型技术在光学元件冷加工中占据重要的地位,是对平面及非球面光学元件进行最后阶段修整抛光的必要手段.现有的计算机控制光学表面成型技术大都基于数控机床来进行.随着机器人技术的发展和广泛应用,将机器人引入到光学元件数控加工领域是一种新的有效尝试.因此,对一种基于机器人的光学非球面柔性抛光技术进行了运动学分析,并建立了控制模型,利用控制模型进行工件加工,获得了较好的加工效果.

Computer controlled optical finishing（CCOS） is important in the optic component machining and it is an essential method to polish the plane and aspheric optic work-piece.Up to now,the CCOS is usually based on the numerical control machine.However,it is a novel technology to use the robot in the machining.This paper establishes a controlled model for the flexile robot polishing.The experiment verifies that the machining effect is very good by using the model.
