| 摘 要： | 在数控加工中,G代码描述的零件加工过程不够直观.为了解决这个问题,提出采用有向几何编程语言GPL(geometric programming language)来辅助G代码进行编程,使得编程变得简单直观.设计了GPL语法规则,并依据GPL语法规则设计实现了GPL解释器,提出一种计算检测码的方法对GPL语法进行检查,创建关键字的属性值表以支持检测码的计算.该方法使GPL语法规则容易扩展,便于解释器的二次开发.采用位运算方法进行参数的冲突检测,增强语法分析器的可扩展性,提高分析速度和效率. |
| 关 键 词： | 数控系统 解释器 有向几何编程 计算检测码 值运算 |

| Abstract: | In NC machining,the procedures of product machining which is described by G code is not intuitive enough.To solve this problem,it is presented that using GPL(geometric programming language) to assist G code programming,which makes the NC programming easier and more intuitive.The GPL grammar rules are designed,and a GPL interpreter is developed based on the GPL grammatical rules.A method of calculating checking-code to check the GPL grammar rules is presented,and a |
| Keywords: | table is created to support calculation of checking-code This method makes the GPL grammar rules easy to extend and makes it easy to redevelop the interpreter A method based on logic position operation to detect conflicts of GPL parameters is presented to enhance the scalability of the parser and improve the analysis speed and efficiency of the parser Key words: CNC system interpreter directed geometrical programming calculation of checking-code bits operation |
