3D process planning has become an indispensable part in intelligent manufacturing system. However, it still cannot meet the requirements of reconfigurability and responsiveness. This problem has become the bottleneck of the development of intelligent process planning. . Based on previous work for machining process planning, the basic theory, algorithm process, module development and system integration of dynamic reconfigurable 3D process model for intelligent process plan is researched. A set of software modules are established and integrated into 3D machining process planning system, and it will obtain leapfrog promotion for the 3D machining process planning system. This will meet the requirements of the 3D process plan of rapid response to the intelligent process planning.. The main research contents are described as follows: Firstly, based on the analysis of the requirements of the diversity and dynamic process information, to be self-reconfiguration method of 3D process model is studied, and the framework model of process route is created. On this basis, the reasoning method is researched based on the machining feature of organizational units. This method involves the extraction of machining information, the retrieval of machining feature and the rule of process reasoning. At last, the dynamic reconfiguration method of three-dimensional machining process model is researched, and the intelligent matching method of process information is constructed.
