基于PMAC的微铣床数控系统中G代码编译研究

摘要

The G-code compiling process of the micro-milling machine NC system based on PMAC is summarized and a G-code compiler module is designed utilizing compiler theory, software engineering concept and VC + + 6. 0 software programming tool. The G-code compiler includes code inspection function and code conversion function, which can compile G codes generated by PRO/NC module of Pro/E into the instructions recognized by PMAC. The G-code compiler module has a friendly interface, and the operation is simple. The machining example showed that the designed G-code compiler can realize the automatic processing of the small components with complex geometric features.%概括了基于PMAC的微铣床数控系统G代码编译流程,利用编译原理、软件工程的思想及VC++6.0软件,设计实现了G代码编译模块程序.该G代码编译程序包括代码校验和代码转换两部分功能,可以将Pro/E数控加工模块(Pro/NC)自动生成的待加工零件的G代码编译为PMAC卡能够识别的指令.该G代码编译模块界面友好、操作简单,加工实例证明该方法能够实现具有复杂几何特征的微小零件的自动加工.
