用户宏程序是FANUC数控系统及其类似产品中的特殊编程功能,用户宏程序由于允许使用变量的算术运算、逻辑运算及提供了条件转移语句和循环语句等,使得编制同样的加工程序更简便、更灵活,是数控技术的重要组成部分。数控编程的此功能与C语言编程的思想相似,利用C语言编程语句,介绍了数控宏程序加工抛物线的方法。总结出宏程序在数控车削非圆二次曲线轮廓类零件的编程方法及技巧。
The user macro program is a special programming function in FANUC numerical control system and its similar products. The user macro program is easy to program the same machining program by allowing the arithmetic operation of variables, logic operation, conditional transfer statements and loop statements. More flexible, CNC technology is an important part. This function of NC programming is similar to the idea of C language programming. By using C programming language, this paper introduces the method of NC macro processing parabola. Summarizes the macro program in NC turning non-circular conic contour parts programming methods and skills.
