摘  要:文中分析了XML解释器的功能结构,探究XML解释器的实现功能。在VC++6.0环境下,依据XML文件信息结构逐一识别、储存加工零件所需的所有操作任务和具体信息;解释器从XML文件中读取加工零件包含的工程,工作计划、工步、制造特征及技术描述、几何描述等信息,进而过滤出几何参数、坐标、刀具等数据信息存储到指定的数据结构中,为DSP控制器内核提供数据源。结果表明XML解释器作为数控系统中的一个单独的功能模块,具有良好的模块化特性,结构简单,功能强,效率高。它将XML文件释译成数控系统内核可识别的信息,在XML文件与CNC系统之间架起一座桥梁。The purpose of this paper is to analyze the function structure of the XML lnterpreter,ana to marc further research on the information processing function of XML interpreter. The method is to create C ++ class corresponding to entity definition in the XM L agreement,it recognize all the needed operation tasks and detailed information stored in part one by one according to the information structure of XM L file by using VC ++6.0. By creating all kinds of object s to implement the function,the XML interpreter reads the project, work plan,steps,manufacturing features,technical and geometric description and so on from XM L file,which are included in part,and then the data information such as geometric parameters,coordinates and tools are picked out and stored in the designated data structure,they can provide data resource for the core of the XM L con- troller. The STEP-NC Interpreter has a property of good modularization,simple structure,powerful function and high efficiency. It connects XML file and CNC system by turning XML file to the information that the core of STEP-NC cont roller can recognize.
