Graphic data information visualization has been a research focus in computer graphics (CG)and visualization field, and graphical data mining, extraction and display are always done with computer graphics knowledge. This study probes into the computer graphics realistic processing technology in computer aided numerical control(NC) lathe turning processing automatic programming system, the application of programming by using computer image processing technology to extract the DXF trajectory curve, the outline of shaft parts and surface construction algorithm is adopted to improve the data processing, generating parts needed for the realistic 3D data model. Combined with OpenGL content for entity rendering of 3D data model, which interactively realized functions of light, material, spray, et al. Through the rotating, perspective transformation, part designers can truthfully observe parts' internal structure, with an intuitive understanding of the whole structure of the designed parts. The experiment results show that the development of graphics realistic application system can efficiently realize lathe turning rendering of shaft parts, and it has the high profile data extraction efficiency and realistic rendering capabilities.
