复杂光学曲面超精密切削
【Abstract】
Based on the fast/slow tool servo, ultra-precision diamond cutting is widely regarded as an efficient and ultra-precise manufacturing technology for complex-shaped optical surfaces. This report explores the complex coupling effects among the machine tools, diamond tools, and workpiece materials, examining the mechanisms by which reciprocating servo motion influences material removal behavior. It reveals the impact of servo axis kinematics/dynamics on the generation of complex-shaped optical surfaces. For the high-quality manufacturing of discontinuous microstructured surfaces, a series of novel techniques, including virtual spindle servo cutting, elliptical servo cutting, and rapid-slow tool collaborative cutting, have been proposed and comprehensively investigated, thereby expanding the kinematic/dynamic boundaries of ultra-precision machine tools in creating complex microstructured surfaces.
基于快速/慢速刀具伺服的单点金刚石车削被广泛认为是复杂光学曲面的高效、超精制造技术。本报告针对机床-刀具-材料复杂耦合作用规律，探讨了往复伺服运动对材料去除行为的影响机制，揭示了伺服轴运动学/动力学行为对复杂光学曲面生成的影响规律。针对非连续光学曲面高质量制造，提出了虚拟主轴伺服切削、拟椭圆伺服切削和快-慢刀协同切削方法，拓宽了超精密车床对复杂微结构表面创成的运动学/动力学约束边界。

【ABSTRACT】
High precision manufacturing of large aperture complex curved surface optical elements is one of the core technologies in the development of modern large-scale optical systems. Manufacturing optics depends on optical processing equipment and technology. Compared with five-axis CNC machine, industrial robots are more flexible, cost-effective and efficient. However, the motion accuracy of industrial robots limits the precision of optical manufacturing. This report will introduce the research progress of optical manufacturing technology based on industrial robots, including Abrasive-Belt Milling, Computer Controlling Optical Surfacing, Flexible Ball-end tool polishing and Magnetorheological Finishing. Some Multi-robot collaboration on large mirrors will be introduced as well.  Moreover the intelligent prediction of removal function is studied for real-time control of the manufacturing process. Finally, the application of optical manufacturing equipment based on industrial robots for large aperture aspherical mirrors, is introduced and the future development is prospected.
大口径复杂曲面光学元件的高精度制造是现代大型光学系统研制的核心技术之一。光学元件的制造依赖于相关的光学加工设备及加工技术，相比于数控加工中心，工业机器人应用于光学加工在运动自由度、曲面适用性、加工成本、批量化制造等方面更具有优势。然而工业机器人的末端运动精度限制了光学加工的精度。本文将介绍基于工业机器人的光学加工技术研究进展，包括基于工业机器人的砂带铣磨技术、小磨头研抛技术、小工具快抛技术和磁流变抛光技术等，同时介绍面向大口径反射镜加工的多机器人协同制造技术。基于机器人光学加工设备，对去除函数的智能预测进行了研究以期实现光学加工过程的实时动态控制。最后对基于工业机器人的光学加工设备在大口径复杂曲面光学元件制造中的应用进行展望。
