This article deals with the research on the features and collaborative process of independent development of key automobile parts. It generally employed concurrent engineering theory and technologies of Internet & Intranet, computer aided design (CAD), computer aided manufacturing (CAM) and product data management (PDM). Field knowledge on independent development of key automobile parts was concluded and a set of concurrent collaborative environment and key enabling supporting technologies that face the independent development of automobile body panel dies were also built up. Meanwhile it introduced the secondary development methods of knowledge based engineering (KBE) to implement the knowledge transformation of designing and manufacturing experiences for an enterprise. The results was applied for the development & production of one of this enterprise's new automobile styles and work well.
