| In order of some new types of weapons, it is necessary to improve designing and product quality of important frame part. Aimed at enhance system frame part mechanical design and manufacturing level, the CAD/CAM integration technology theory is combined to advanced integrated software UGII. The researching route and main focuses of this paper are presented as follows:a. On the base of summarizing lots of international literatures and analyzing the actuality and the evolution trend of CAD/CAM technology. By studying and applying the main technology, the researching method, i.e., Three-dimensional entity model generation, analysis, manufacture technology design and Numerical-Control machining is put forward to develop some new types of weapons.b. Above all, the mostly tasks of CAD/CAM are summarized in existence condition. Some function and characteristics of CAD/CAM integrated software UGII correlative module are discussed in detail.The design and manufacturing collectivity flow of part is established.c. The method of establishing parametric entity based on the characteristics is confirmed, including theory and method. The part 3D entity model based on sketch, form feature and feature operation is completed.With CAE module of software, the model is elementary analyzed.d. According to the structure characteristic of system frame part , the NC machining technology scheme is designed to adapt to the existing NC equipments and tools case.The particular setting are drawn for rough machining and finish machining with the CAD/CAM platform. The machining tool track is analyzed, corrected and optimazed with machining simulation module.e. On the conditions of NC equipments,the machine data file is completed.With the machine data file,the NC machining code is generated.The NC programs being input into machining center,the process is done,thus the qualified products are produced.The results show that the research on integration technology of CAD/CAM improve machining efficiency are correct.
