Paper Abstract

Large diameter aspherical reflector polishing technology is a kind of technology which has big difficulty, long process cycle and high production cost. Therefore, the polishing efficiency and accuracy are reduced. But now the intelligent large diameter aspherical reflector polishing technology greatly increases the polishing efficiency and accuracy. This paper introduces intelligent large diameter aspherical reflector polishing technology. Intelligent large diameter aspherical reflector polishing technology is a technology to make the skill of the advanced optical machining person digitization and quantization. Compared with traditional optical machining technology, intelligent optical machining technology makes the judgement of the optical shape more accurate, control of the process more reliable, machining efficiency accuracy greatly improved. Take 1.2m diameter aspherical reflector as an example. Before manufacture, PV of the mirror is 2035.531nm and RMS of the mirror is 192.392nm; After simulation, PV of the mirror is 1598.222nm and RMS of the mirror is 133.216nm; After manufacture, PV of the mirror is 1503.122nm and RMS of the mirror is 133.110nm.The PV error between simulation and manufacture is -5.95%.The RMS error between simulation and manufacture is -0.08%.These results prove that intelligent large diameter aspherical reflector polishing technology is high efficient and accurate.
