Virtual Reality（VR） technology is applied for the Numerical Control （NC）milling manufacturing system, based on the Visual C ＋＋ development platform. According to the structure feature and main element units of NC milling machine in the virtual scene, the three-dimensional virtual model of 3-axis NC milling machine is constructed, on the background of FANUC NC system, using OpenGL software technology. The corresponding NC milling manufacturing simulating system is designed, especially the man-machine interface and the accomplishment method of NC manufacturing program executing process are introduced in detail. Finally, the vivid simulating example is presented, which has satisfactory effect. The proposed virtual manufacturing system can be widely apphed for the verification of NC program, the education and training of NC technology.
