The Research And Development Of Tool For Building Part Library Based On Pro/E

The part library which includes standard part library and common part library has been in wide use in CAD systems, building the part library is various and trivial. For improving the efficiency of design, a tool for building part library should be worked out. Based on the project of components'standardization system for China Aerospace Standardization Institute, the thesis focuses on the development of the tool for building feature library and part library, and implements the main function with program. Main work includes as following: Firstly, on the basis of explaining the evolution and theory of parametric modeling and the development and use of standard part library, this thesis analyzes the necessity of tool for building part library, and outlines the function objects of the system. The advantage of parametric modeling is explained by comparing the template modeling technology and the feature modeling technology. Then, the UDF modeling is selected as the method of tool for building part library after describing several parametric modeling which is proved by Pro/ENGINEER, finally the UDF modeling technology and process are described in details. Combined feature technology with OO(Object-Oriented), there is classification of feature. And the feature library is also designed, so the tool for building feature library is worked out. Finally, there is the design of part library and the development of the tool for part library with analysis of the model of part library. In this article, there are three key technologies including parameter matching, the realization of pattern and the editable report in Pro/ENGINEER are described from the theory to the realization. Ultimately, the purpose of the system is implemented. A conclusion is drawn for full text, and it is pointed out that the research direction in tool for building part library developing in the future.
