The Development Of Powder Metallurgy Mould CAD System And The Investigation Of Key Technology

Based on unigraphics platform and the project supported by guangxi science and technology department, the following investigations have been carried out in this paper.(1) With the mould design principle of powder metallurgy, it has been profoundly investigated and a new classification in the main parts of sizing-mould also has been provided in this paper.(2) The overall architecture of the P/M CAD system has been set up, and the f unct i onal modules of the system have been f i n i shed under the environment of software and system engineer and IDEFO methods, meanwhile, the data management and transfer mechanism have been established between the P/M CAD system and unigraphics.(3) The methods of development and relization are based on the prof oud i nvest i gat i on on the software development using unigraphics and the mould design principle of powder metall urgy. By the program of UG/Open API, all interfaces have been designed, some key technologies also have been solved and the system has been basely carried out.(4) At last , to i ntroduced the P/M CAD system , this paper designs a small sized bush.At the same time, on the base of studying the mould structure of powder metallurgy deeply, the key technology of user define feature has been profoundly investigated and the part library of powder metallurgy has been finished.
