把同类型零件按相同工序内容分组,运用同一设备,同一工艺装备、同一工艺方法及其相同的调整方式方法进行加工生产,这就悬最初形成的成组加工概念.现在它已被大大引伸发展,甚至越出了工艺范畴,成为涉及全部生产过程中各个环节(包括产品设计,工艺设计、计划管理等生产管理领域),并已逐步形成以零件成组化为基础的成组技术(GT)概念,成为一门综合技术。最初应用成组加工手段之一的是成组夹具,以后随着人们认识上的深化和成组技术的发展和演变,出现了为成组加工设计的机床设备.同时一些高效和自
The same type of parts grouped according to the same process, the use of the same equipment, the same process equipment, the same process and the same method of adjustment methods for processing production, which hung over the initial formation of the group processing concept now it has been greatly extended development , And even beyond the scope of the process to become involved in all aspects of the production process (including product design, process design, project management and other production management), and has gradually formed a group of parts based on group technology (GT) Concept, become an integrated technology. One of the first applications of group processing tools is the group of fixtures, and later with the deepening of people’s understanding and the development and evolution of group technology, machine tools and equipment designed for group processing have emerged,
