Research About The Macro Program Based On FANUC 0i CNC System

Along with the rapidly development of CNC technology and CAM software, manual programming has been mainly replaced by CAP.So many people ignore the importance of manual programming especially macro program. A macro program can workout 3-D curved face program easily, and the program will be concision and good at universal property. If the parts have same shap but different dimension, you can use different univerical value when transfer a macro program.The advantage of a macro program can incarnate on machining such as hole system, adumbration, cylinder, sphere, R face. This article studys FANUC 0i CNC system, that based on the speculative knowledge and application. This article comes down to the mathematical basement, complie, and provided one typical translation method, which can be used to all the Macro Program and B program about macro program. And this article use two examples.Hope this article will be useful for the application and extension of macro program.
