Analysis And Design Of Clothing CAPP System

Along with the development of global economic integration, the requirement to promote informationization level for China clothing enterprises is more and more demanding. The informationization of clothing design and production mainly includes: technology about design information, technology about structural design and technology about production craft design. Currently, the research of CAD technology on structural design of clothing style is quite mature, but the research of CAPP is just beginning. And CAPP has become an important part in the clothing manufacture system and needs Researching and Application urgently. This project will help clothing enterprises to accommodate the trend "Many kinds, Small batch, High quality and prompt delivery".This essay analyzed the main content of the informationization of clothing design and production. It studied clothing CAPP system with computer technology, graph technology, database technology and the theory of clothing project, constructed the digitized clothing production craft system and key researched 2 modules: The clothing production craft information encoding designs and clothing production assembly line arrangement optimization.The CAPP system, which is constructed on the research of requirement of clothing production craft system, is divided into the clothing craft input system, the craft decision-making system, the craft search system, the craft management system, the craft maintenance of resource and the technological document craft coding production technological document output system, the database management system and so on modules, and further discussed the modules basic functions.The bottleneck of CAPP system is the lack of uniformed "language". The essay researched on the information coding of the clothing production craft, outlined the code definition covering the information carries on the clothing craft process, classified, performed and saved all above information in the form of digit or letter. Together with certain coding rules, established the relations among every kind of craft information, carried on the graph information encoding, the technological document code, the clothing GT classification code and the model code structural design, and designed a set of reasonable clothing CAPP digital definition regulations, which will help to establish the digital clothing craft system.The other important part is the craft decision-making system in clothing CAPP system. The method of assembly line arrangement in clothing profession production is outdated at present. The optimization of clothing production assembly line arrangement can enhance the market competitive power of clothing enterprises. The essay researched on the settlement of optimizing the arrangement of working procedures on clothing assembly line with self-adaptive and choose linear programming model as selection. Considering the different equipment and different order of each processing, based on the rhythm of the assembly line and the requirement of craft system, it balanced the operation time of different working unit. It provided the detailed optimizing steps with an example of order arrangement.Together with the research on the digitized clothing production craft information technology, this essay constructed the overall frame of clothing CAPP system, designed whole set of code schemes and obtained one effective assembly line optimization method. All these will benefit the advancement in the research of digitized clothing engineering.
