为此，本文针对上述问题，研究了通用数控代码编译器的技术构成，开发出了一个具有通用意义的NC代码编译系统。
For this, this dissertation develops a general concept of nc Code Compiler, based on studies the technical structure of general nc Code Compier.
先从分析一般数控代码格式入手，然后用扩展巴科斯范式表达从中提取的文法规则，使后续对译码模块的研究建立在编译原理的基础上。
It begins with analyzing common CNC code format and then expresses its grammar with EBNF, so continuous research of coding module is established on compiler principle.
对AP238文件的译码处理不能像g代码那样逐行解释执行，而只能采取编译的方法，因此，STEP - NC数控系统的译码处理系统称之为编译器。
The decipher of AP238 file can't explain and execute line by line as G Code, and can only compile, thus the decipher process system of STEP-NC numerical control system was called as the compiler.
