| 摘 要： | 语法检验在CNC系统中占有相当大的比重,尤其是在数控系统的自动或MDI方式下运行。NC代码的正确与否直接关系到能否正确完成数控加工,而现在国内自主开发CNC系统的语法检验功能还不够完善,并且检验方法也不尽科学。针对五轴联动高档数控机床,参照双数组Trie算法的原理,提出了基于双数组Trie算法的关键字预处理技术,并将其成功地应用在语法检验之中,从而使得对NC代码的语法检测更加准确。 |
| 关 键 词： | 双数组Trie树算法 关键字预处理 语法检验 CNC |

| Abstract: | Syntax check occupies considerable proportion of the CNC system,especially when running automatically or in the MDI mode.Whether NC code is correct or not is directly related to the ability to properly complete the process.But now in most of the CNC systems which are developed by our country,the syntax check feature is not perfect,and the testing methods are not exactly scientific.In this paper,according to the principle of double-array trie tree method,we propose the technology of Keyword-preprocessing bas... |
