3D CAPP Deepening Of Application In Assembly Industries

Process design is the connecting bridge of product designing and manufacturing, which is the key link in manufacturing system, impacts a lot on product quality and production cost. Digital manufacturing process design and management is an important component of enterprise "rejection of drawing" one of the core, "rejection of Debt Tables". Driven by the State Ministry of Science and technology, after the efforts during "95" and "15", the autonomous development of CAPP software products occupy a leading position in the domestic market. But the traditional CAPP software card processing mode, the majority of the enterprises CAPP application remain in the process card editing, statistical summary of the information technology, technological process and permission management and control,As more and more enterprises using 3D CAD in product designing, a series of problems that need to be resolved, such as how to integrate the process and 3D CAD integration, how to design marching process and assembly process based on 3D CAD and so on. Process planning based on 3D product model has become the pressing needs of the enterprises. Particularly in assembly enterprises which use manufacturing line the demand is urgently, how to organize production according to the station to increase the degree of automation of the workshop, how to structure layout of the factory, how to beat process and production optimization and so on.Date main PLM foreign companies such as Siemens, PTC, and Dassault can provide digital manufacturing solutions. Among the customers we have contacted, advanced assembly manufacturing enterprises in the preliminary application of 3D CAPP. For example, Chery automobile, Assembly and welding process using Dassault DELMIA in digital manufacturing process design, focused on digital simulation and modeling of treatment plant. Most domestic manufacturers still use the traditional CAPP as card editing tools, but more enterprises have gradually realized the traditionalCAPP cannot meet their needs. Shenlong automobile, have been gradually discussion on the application of 3D CAPP in their enterprises. But most manufacturers could not afford the high cost of foreign 3D CAPP solutions. With the deeps inside of manufacturing line and assembly manufacturer as well as the study of CAPP, MPM,3D technology, we study on 3D structure process based 3D CAD, mainly related to the 3D structure model building and 3D visualization processing, workshop layout, line balancing research on key technoligies, demand analysis and system realization of complete the system.The application of research achievements is of great significance to consolidate and enhance china's positionof CAPP products, improve the technolo gy of manufacturing enterprise productinnovation ability, shortening the product d evelopment cycle, improve marketingcapability.
