Résumé

The Chinese economy has increased quickly and continuously in recent years. Manufacturing is an important part of Chinese industry. The enhancement of modem manufacturing technology is becoming an important issue. The aim of the present thesis is to develop nonstandard (over-stiff) tools5 CAD/CAE/CAPP/CAM integrated system. This will involve integrating modern information technology, manufacturing technology and management technology. The thesis objective is to propose a totally new and integrated design, analysis and manufacturing system. This would provide to manufacturers a capability to carry out the incorporation of CAD/CAE/CAM systems.

Many enterprises and universities have developed standard CAD system tools5 in recent years in China. But in regard to nonstandard complex CAD/CAM tools5, there is still much to be done. After more than one year investigation and research, a great quantity of information and data has been assembled, thus setting a solid foundation for completing this project successfully.

This thesis considers in detail the problem associated with non-standard over stiff end milling cutters to illustrate the design approach used and its implementation. It uses a feature based model constructing technology and applies the CAD and finite element analysis together with relevant theories and technologies for processing and manufacturing. The thesis completes the development of non-standard complicated tools5 CAD \CAE \ CAM integrated system.

The thesis consists of six chapters, dealing with the project's background, system's design and structural design requirements, finite element analysis, CAM, and some concluding remarks based on what was learned during the thesis work. The project's kernel technology is to use finite elements method to analyze the nonstandard complex tools' models using ANS YS large-scaled finite element analysis software.
