With the development of science and technology,the demand for precise optical components is increasing in many industries.How to realize the quantity and quality requirements of optical components efficiently and at low cost needs to be solved urgently.At present,the traditional optical processing method is the numerical control machine tool,and the new optical processing methods such as magnetorheological polishing and ion beam polishing.This paper takes the equipment volume,economy and efficiency into account and finally adopts the industrial robot polishing.By quantifying and digitizing the optical processor's experience to analyze the path planning,design and write the corresponding instruction code.Considering the inadequacies of the previously designed polishing tool,this paper redesigns and improves them,and the polishing experiments are carried out by installing the designed polishing tool on the execution end of the industrial robot,the efficiency and feasibility of the industrial robot wheeled polishing are verified from both theoretical and experimental aspects,and the theories and experiments in the polishing process of optical components are studied:1.Firstly,the current development status of optical polishing at home and abroad are introduced,and the theoretical basis of computer controlled small tool polishing technology is highlighted,based on the Preston hypothesis,the material removal model and removal characteristics are theoretically analyzed and the dwell time is iteratively calculated;And the pressure in the wheeled polishing process is simulated based on the Hertz contact theory.2.Based on the Preston hypothesis,add pressure control structure to the polishing tool;According to the previous experimental results,noting that the tension of the polishing belt is not good,so the new mechanical structure of the polishing tool is redesigned;At the same time,the stability and removal characteristics of the polishing tape material have a direct influence on the final surface shape of the optical components,this paper studies the polishing tape materials.3.The experimental platform is built,and the coordinate system of the industrial robot used in the experiment is analyzed and the space coordinate conversion is calculated,considering that most optical components are aspheric surfaces,the corresponding Euler transform is calculated,and the corresponding instruction code is designed,and the robot instruction program is designed and generated.Polishing experiments are carried out by using plane and spherical surface,and the removal characteristics of the removed areas are studied,which verifies the feasibility of the new polishing tool.The research results show that using the industrial robot-based wheeled polishing method in optical polishing is feasible and efficient,and it has great potential for polishing of medium and high precise components.
