Applied Research On Macro Program In Quadrics Milling Based On FANUC 0i Cnc System

In the macro programming, using variables of similar to a computer high-level programming language, make programming more easy and flexible, can achieve the functions of common programs difficult to achieve, greatly expanded the areas of manual programming. For some typical secondary surface milling, CAD / CAM software be able to automatic programming, but the program is often very long, poor technology, poor readability. Programs written by macros, which is short and simple, occupy less system memory, versatility, easy to modify and edit , high efficiency processing , so are used widely.In-depth study line approximation algorithm in Non-circular curve and Quadrics straight, which is based on FANUC 0i CNC system macro program., completed Non-circular curve and Quadrics Approximation interpolation successfully, carried out some typical tests of targeted successfully.
