In our country, the common problems of the quenching machine tool in manufacturing are lack of systematic and modular. In design and manufacturing process, there is no designing platform for the whole life cycle of the machine tool. Aimed at this problem, this paper construct a intelligent designing platform for the general quenching machine tool based on the whole life cycle. The platform can control the whole life cycle of the quenching machine tool. It used NEI biological network technology on the machine tool designing CAD system module. The platform realizes the automatic discovery, negotiation and combination of the designing resources and design knowledge. The platform generates a self-organization, self-aggregation, collaborative intelligent designing environment. The platform broke the limitations of the traditional machine tool design and solved the problems lacking of a systematic modular to the quenching machine tool in manufacturing industry .
