Abstract: To deal with the problems on repetition, disorder, scattering and production efficiency of Numerical Control (NC) information management, product digital design and NC machining integrated information model based on Product Data Management (PDM) was proposed. The integrated model of NC machining information was set up from the perspectives of Computer Aided Design (CAD) 3D modeling, part information management, product Bill Of Material (BOM) management, part Computer Aided Manufacturing (CAM) management, creation of NC program, Shop Scheduling and NC database. The PDM-based integration of product digital design, shop scheduling and manufacturing was realized by integrating product structure information and part information, associating shop scheduling and NC machining information, and using serial communication method between NC systems and computers. The proposed method was applied in practical project, and the research results showed that this method was feasible and effective.
