CNC machine tool is an important manufacture equipment. To improve its design level and capability, it is necessary to import new technology and design method in design and development of CNC machine tool. To apply virtual prototype, a new engineering design theory and method, in design and development of CNC machine tool, specific implementation process of CNC machine tool virtual prototype based on the concept of virtual prototype is proposed. Analysis and compare on the features of the distributing software platform to implement this process and UG integrated environment are carried out. Taking development of a new type of CNC milling machine as an example, research on construction and simulation process of CNC machine tool virtual prototype in UG integrated environment is conducted. Then, research on numerical model, assembly, motion simulation, structure analysis and manufacture simulation of CNC machine tool virtual prototype are carried out and corresponding illustrations are provided. The research indicates that construction of CNC machine tool virtual prototype and comprehensive simulation on it can effectively completed by adopting the function modules of UG and total optimization of designed machine tool can be achieved. This research provides a feasible advanced method for design and development of CNC machine tool.
