CAD / CAM is a comprehensive technical complexity of the system engineering, which involves many disciplines such as computer science and engineering, computational mathematics, computer graphics, data structures and databases, simulation, CNC, robotics and artificial intelligence disciplines and technologies as well product design and manufacturing expertise. CAD / CAM technology makes the design and manufacturing process the application and popularization of the machinery manufacturing industry toward automated, integrated, intelligent, virtualization, network direction. This paper focuses on the CNC milling carving the design and development of CAD / CAM systems, expand research on the CAD / CAM technology, focuses on the design implementation method and key technologies of CAD / CAM system, and then combine the research content detail CNC milling carving CAD / CAM system design and implementation, and finally a summary of the development trends of the development direction of the CAD network CAD and manufacturing mode. The main content of this article is organized in three parts: The first part is a CAD / CAM systems. This part of the first analysis of the structural framework of the CAD / CAM software system, the main task of the design process and design principles, and then studied the geometric modeling, finite element analysis, optimization design, CNC programming CAD / CAM system to achieve the key technologies for the specific CAD / CAM system designed to provide a sufficient theoretical basis. The second part discusses a specific CAD / CAM systems - CNC milling carving CAD / CAM systems design and implementation, and the key issue. Given the specific features of the system modules divided into various modules according to the demand of the project development, and then discussed in detail the design of each module; finally discusses the basic principles of the numerical control technology, processing technology, tool path generation, editing, verification key issues to do further research. The third part starting from the CAD and manufacturing technology development trend of network CAD and manufacturing model of the 21st century, has done a detailed analysis of the network of CAD technology Computer Supported Cooperative Work (CSCW), explores the characteristics of various manufacturing model mutual relations and trends. From theory, implementation, and development trend of three levels of CAD / CAM technology to do an in-depth analysis of research, these theoretical and practical knowledge on the development of other systems have a certain reference value.
