Part Cnc Programming Method Based On The Cad / Cam Technology Research

CNC technology and CNC machine tools in today's machinery manufacturing industry has the important status, display its national infrastructure in the industrial modernization of the strategic role, and has become a traditional mechanical manufacturing industries to transform and enhance the implementation of automation, flexible, integrated production and an important means of marking, the NC machining technology of the whole process is currently manufacturing personnel to grasp the importance of knowledge.This paper through the analysis of numerical control technology, CNC programming based on the CAD / CAM software, automatic programming, a software post-processing document production, NC simulation, CNC machining and other general steps. Using the UG5.0 software through the most appropriate form to design parts model, analyze according to the craft to make the best processing method by milling programming based on Sinumerik, 802S / 802C CNC system were after processing procedures document preparation, solved the complex parts in the shape and manual programming difficulties and the parts in the software for numerical control processing the program cannot be derived, for all CNC machining and other problems.
