超精密切削、磨削和蚀除加工,简称超精密加工,是以材料科学为基础、制造工艺为中心的综合技术,是当代加工技术的重要发展方向。现代加工技术的发展大体有两种趋势:一是加工过程(或称加工方式,即系统加工技术)的研究,如成组技术、自动线、柔性制造系统(或单元),甚至无人工厂,重点是求得最大生产率或经济效益;另一是加工方法(即固有加工技术)的探讨,如特种加工、少无切削加工、精密加工以及超精密加工,主要是深化加工特点,以提高加工精度和表面质量。
Ultra-precision cutting, grinding and etching process, referred to as ultra-precision machining, is based on material science, manufacturing technology as the center of the integrated technology is an important development trend of contemporary processing technology. The development of modern processing technology in general there are two trends: First, the processing (or processing methods, that is, system processing technology) research, such as group technology, automatic lines, flexible manufacturing systems (or units), or even no artificial plant, the focus Is to find the maximum productivity or economic benefits; the other is the processing methods (that is, the inherent processing technology) of the discussion, such as special processing, less no cutting, precision machining and ultra-precision machining, mainly to deepen the processing features to improve processing accuracy and Surface Quality.
