机械外文翻译--编制机械制造工艺规程中几种先进技术的综合应用(编辑修改稿)内容摘要：

aracteristics to group, classification and code for each of the ponents, and then establish the typical ponents of each type of library and the processing technology of group library. Processing technology to develop parts in groups of two ways: 1) The virtual part method. In a parts group, the first we design a part of this group which can contain all the geometrical features of the virtual part, and require the tribe owns the processing of all the parts needed for processing the surface. Then we press the virtual part to technological design. That is the group technology of group parts. 2) The posite process route method. Firstly , we find a the most plicated structure, the longest part of process lines represented in the part family, and then join in the other parts which is representative and not processes in the family. Obtain a whole family to meet the processing requirements of plex parts process route. 2. Computer aided process planning CAPP [3] 1 CAPP technology overview and the role of advanced manufacturing mode Machinery manufacturing process design is the most active factor of the production activities. It with production and business types, product mix, process equipment, production technology and technical management of the level of internal factors has inextricably linked. Process design is a strong empirical, technically demanding, a wide involving range of integrated disciplines. It is the bridge from design to product and an important position in the machinery manufacturing work occupies. It is changed by the time, places, conditions and other factors changed. For a long time, the working practices were prepared using the traditional manual method. As market petition intensifies and social needs diverse and individualized, making mechanical and electrical industry increasingly to multispecies, small quantities of direction. So does electrical equipment. Process design manual mode of operation neither meets the changing requirements of modern production breeds, nor matches with advanced means of production and management system. With the improvement and popularization of puter applications and the development of group technology, puteraided process design techniques have emerged to bee a modern process design and process management a powerful tool. CAPP development and research was begun from the last century began in the late sixties. In the field of manufacturing automation, CAPP39。 s development in terms of relative CAD and CAM is the latest part. The world39。 s first study of CAPP countries are Norway in 1969, and in 1969 Norway launched the world39。 s first a CAPP system AUTOPROS。 in 1973, Norway officially launched the mercialization of AUTO PROS system. In the CAPP history , a landmark of the CAMI introduced CAMI39。 S Automated process planning system in 1976. We use the first letter of prefix, called the CAPP system. Currently, although there are different interpretations of law about the acronym CAPP, called the ComputerAided Process Planning as CAPP has bee the accepted interpretation. With the level of machine production technology development and market demanding, Computer Aided Process Planning (CAPP) as the bridge of connectivity product design (CAD) and manufacturing (CAM) links product design and production management (MRPII / ERP), and organize production and ensure product quality, improve labor productivity, shorten production cycles resulted in more and more direct impact. Replacing the CAPP to the traditional process design has bee a necessity and the importance of its machinery manufacturing industry, reflected in the following points: (l) it libe。
