Post- processing is the The knife bit file preprocessing production process converted to the specified machine implementation of the NC code . But the diversity of the numerical control system on the market , leading to the traditional post-processing is increasingly unable to meet the new demand , and post-processing the low level of generalization . CNC machining process , the operator in terms of post- processing to spend a lot of energy , and can not be achieved very good results . Therefore, we need to study a generic post-processing system , to meet the different needs of the actual production . In this paper, the status of the universal post processing analysis , as follows : ( 1 ) According to the different structure of CNC machine tools to the classification of institutional analysis and kinematic analysis from the point of view of kinematics CNC machine tools , machine tool building kinematics model , and then according to the graphics transform basic principles of the CAD system , analyze and summarize the post- processing algorithms for a variety of machine tools agency . (2) to study the characteristics of various mainstream CNC machine tools and CNC system , interactive way to configure a generic machine configuration file to various mainstream CNC machine tools , CNC code output . (3) the use of object-oriented programming software to write generic post- processing system . Finally, the system running , testing to meet the original design requirements , i.e. able to be output can directly drive the NC program of the machine tool . CNC machining generic research and development of post-processing system , the operator need only machine information input program , you can complete the process of post-processing , so you can save a lot of time in the production process , and post-processing process becomes simple , easy, improve labor productivity , to ensure that the enterprise benefits , which has a very important significance .
