Intellectualized large diameter aspherical reflector manufacture technology

摘要

Large diameter aspherical reflector machining technology is a kind of technology which has big difficulty, long process cycle and high production cost. Therefore, the machining efficiency and accuracy are reduced. But now the intelligent large diameter aspherical reflector machining technology greatly increases the machining efficiency and accuracy. This paper introduces intelligent large diameter aspherical reflector machining technologies. Intelligent large diameter aspherical reflector machining 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 and machining accuracy greatly improved. Take 1.3m diameter aspherical reflector as an example. Before manufacture, PV of the mirror is 8722nm and RMS is 1230nm. After simulation and manufacture, PV of the mirror is 4948nm and RMS is 358nm and PV of the mirror is 5390nm and RMS is 356nm respectively. The PV error between simulation and manufacture is +8.93%. The RMS error between simulation and manufacture is -0.56%. These results prove that intellectualized large diameter aspherical reflector manufacture technology is highly efficient and accurate.
