【摘要】：随着光电通讯、生物医疗、航空航天等技术的飞速发展,高性能、高精度、高集成的零件及模具不断涌现,其不仅结构复杂,加工精度和表面质量要求高,而且大部分都属于硬、脆难加工材料,传统的抛光方法难以胜任。基于可控柔性理念的抛光技术,为上述零件的高效率和高精度抛光提供了一种新思路,逐渐成为超精密抛光的重要发展方向。首先,介绍了可控柔性抛光技术的基本概念,并就柔性执行装置、柔性"研抛模"、柔性控制系统三种可控柔性抛光方法的柔性可控原理、结构特点以及国内外研究现状等分别进行了综述;其次,对以上可控柔性抛光方法的加工原理、材料去除、抛光精度等进行了深入分析与比较,进一步阐述各类方法的优缺点;最后,对可控柔性抛光方法基本理论的系统研究、抛光精度和效率的提高、抛光工艺的复合化和智能化以及智能材料应用等方面的发展趋势进行了展望。
[Abstract]:With the rapid development of optoelectronic communication, biomedicine, aerospace and other technologies, high performance, high precision and high integrated parts and molds are emerging, which not only have complex structure, but also require high machining precision and surface quality. And most of them belong to hard, brittle and difficult to process material, traditional polishing method is not competent. The polishing technology based on controllable flexibility provides a new idea for the high efficiency and high precision polishing of the parts mentioned above, and gradually becomes an important development direction of ultra-precision polishing. Firstly, the basic concept of controllable flexible polishing technology is introduced, and the flexible controllable principle of three kinds of controllable flexible polishing methods, such as flexible execution device, flexible "polishing die" and flexible control system, is introduced. The structure characteristics and current research situation at home and abroad are summarized respectively. Secondly, the machining principle, material removal and polishing precision of the above controllable flexible polishing methods are analyzed and compared in depth, and the advantages and disadvantages of the various methods are further expounded. Finally, the development trend of the basic theory of controllable flexible polishing method, the improvement of polishing precision and efficiency, the combination and intelligence of polishing process and the application of intelligent materials are prospected.
