CNC系统中宏程序设计语言研究

宏程序是现代高性能数控系统中的强大功能之一。联合运用它和ＣＮＣ系统中的其它功能，能够完成诸如孔群之类的复杂加工，而且对用户来说，编程非常简单。本文采用巴科斯范式（ＢＮＦ）定义了ＣＮＣ系统中宏程序设计语言文法。在此基础上，设计了宏程序的词法分析、语法分析及解释执行算法和程序。最后分析了一个应用实例。

STUDY ON MACRO DESIGN LANGUAGE IN CNC SYSTEM

Macro is one of the most important functions in modern CNC systems. By use of it and other functions in CNC system,complex machining such as group holes can be simply completed,also to user, programming is very simple and the parts program is short.In this paper,according to BNF,the language syntax rule is defined.On the basis of the syntax rule, the program for morphology analyses, the program for syntax analyses and the program for executing the macro are designed. At last, an application is presented to explain the algorithm.
