Research & Application On Management Of Information Of Assembly BOM Based On CAD

During the development of enterprises information, many kinds of information management systems have been presented. Further researches on these information management systems reveals that the BOM is unexceptional the essence of information integration about products. But how these BOM information of the systems come into being? Analysis indicates that these BOM information is based on the designing results in CAD system. So it is necessary for enterprises to integrate these information management systems into some CAD systems. Only by this way can we utilize the BOM information in CAD systems, which is of practical significance. Generally, all products are assemblies of many parts, so the management of assembly BOM information about products plays a great role in whole enterprises BOM management. The thesis firstly researches on the importance of BOM management in CAD, and analyzes alternant character and contents between CAD and system of BOM management, and expatiates on basic character of model of CAD assembly, and brings forward general designing project of achieving information management of assembly BOM based on CAD according to anterior analysis and practical requirements.The thesis regards UG as the instance of CAD software, expatiates basic theory about BOM management, and presents three methods of UG secondary development, which are respectively UG/Open UIStyler, UG/Open MenuScript and UG/Open API. The author brings forward a method of object-oriented in order to achieve the integration of UG and system of BOM management and information coding based on UGII on the basis of project of whole designing mentioned above. The thesis also presents key technology for management of assembly BOM, such as traversal algorithm of assembly tree, achievement of information coding and application of database technology.At last,to verify the research described above,the practical examples of programs of UG and MIT PDM are given which are developed by author. The achievements of our research are reliable by analyzing the function of software. Furthermore, project of general designing which is brought forward by author can satisfy the demand of system, it has the characteristic of suiting for different software platform, and has resolved the problem of BOM management of different condition, and has integrated different CAD software.
