数控专用加工代码O代码的功能实现

The Functional Realization of O code in Numerical Control Specialized Process Code

为了实现开放式机床控制数控系统NC代码解析运行的灵活性功能要求,提出了加工代码的控制流语句O代码的实现。通过对数控系统中的解析器模块进行分析,运用在linux平台下面的C++面向对象语言设计方法,本人将原有的解析器模块用类封装重新进行设计,对部分需要增强功能或是改变实现方式的子函数予以重新编写,提出了使用特有的数据结构封装代码状态数据,添加了统一的控制流语句、跳转功能,改良了代码解析的过程,提高了数控加工运行的灵活性。

to reach the agility functional demand of the NC code interpreter which is the open architecture CNC system＇ s sub-module, a stream-controlled sentence named ＂O code＂ in the NC code is presented. After analyzed the interpreter sub-module in the CNC system, used the C＋＋ oriented-object language under the Linux platform, I redesign the interpreter module with class encapsulation, rewrite the sub-functions which are needed to enhance function or change the implementation, presented to use specific structure to capsule the status data, added uniform stream-controlled sentence and jump-like function, improved the process of the NC code interpreting, advanced the agility of the NC processing.
