| 摘 要： | 针对虚拟加工系统的数控程序解析问题,提出一种通用数控程序解析方法.通过分析不同数控系统的数控程序格式,设计了规则数据库.利用正则表达式进行语法分析,提出了建立语法规则方法和语法分析算法,以及基于调用堆栈的子程序处理算法.设计了数控系统定制界面,以便将现有的解析器扩展到新的数控系统.开发出一个通用数控程序解析器,并验证了所提方法的有效性,为虚拟加工系统的实现提供了技术支持.

| Abstract: | Aiming at the problem of Numerical Control(NC)program interpreting in virtual machining sytem,the key techniques of general NC program interpreting was proposed.Based on the analysis of program patterns of different NC systems,a rule database was designed.The syntax analysis was performed based on regular expressions.The establishment methods for syntax rules,the syntax analysis algorithm and stack-calling-based subprograms processing were proposed as well.Then customization interfaces were put forward to e... |
