Research And Application Of Process Information Management Based On PDM

With the gradual development of enterprise's information construction, the demand for CAPP system of enterprises, no longer confine to its solving the problem that technologist fill in the craft card, it considers to be mostly, creation and flow and effective management and maintenance of process information in the life cycle of whole product. So, it is importance with realistic significance that how to accomplish standardization management of process information.In this thesis, studies the model of process information management,based on PDM integrated process information management mode and its system structure and some key techniques under this environment. The main contents include the following:Firstly, the model of process information management based on analyzing the characteristic of process information is established, and the implementation method of this model is analyzed and the solution that based on PDM integrated process information management mode is put forward. The process information integration frame based on PDM is established, furthermore, adopt the integrated mode with the interface function and DDE ,COM technology to establish the system structure of the process information management based on PDM.Secondly, the data interchange among different systems in the process information integration frame is expounded emphatically, and the commutative way of various kinds of information is discussed, furthermore, on flow management of PDM basis, the data interchange mode based on task is put forward, and adopt the mode of middle database and utilize interface function to realize data interchange of integration system.Thirdly, management of process information with function of PDM is discussed and organization and management of process information based on product structure tree is put forward, furthermore, the course of technological design is managed by means of project management of PDM.
