The Development And Design Of CAPP For Textile Machine

CAPP is a major component in CIMS. It not only acts as a tie which joins CAD and CAM systems together, but also keeps close links with other sub-systems such as MIS, MRP, etc. in CIMS. Therefore, CAPP has been regarded as an important research field of modern manufacturing technology. For many years, a lot of new theories and methods have been put forward in this field, but the application coverage of CAPP is still very limited. In fact, almost all of the CAPP systems are developed as specialized system for special parts (such as polyhedrons, cylinders), and some of them cannot be used under network circumstance, so the data consistency and integrity by CAD and CAPP cannot be assured. Thus there is immediate significance in further promoting the practicality of CAPP technique while reinforcing the study of CAPP theories.In this dissertation, the current achievement of domestic and worldwide research and existing difficulties of CAPP is summarized. Based on the principle of practicality and universality, the careful analysis and study of this system has been given in this thesis in combination with the process planning of textile machine. This system is designed to be Client/Server architecture and utilizes series advanced computer techniques; also, it combines the experience of several kinds of CAPP systems having developed together. This system makes the whole product applied subject and several database as the core. Through utilizing a variety of supporting tools, it can be used widely in the framework system of interchanging CAPP in all kinds of enterprises at different levels or different process sectors that combine the process design with information management as a part in an enterprise.
