摘　　要：简要介绍了STEP-NC标准,分析了使用XML表达STEP-NC程序中信息的优越性;提出了STEP-NC数控程序解释器的基本框架,并阐述了各组成模块的功能;针对STEP-NC程序解释器实现的关键问题,设计并实现了信息提取与显示方式、路径规划和切削仿真等功能模块;在Visual C++6.0环境下实现了该解释器的功能,并通过STEP-NC标准中的1个测试件,实例验证了本软件的正确性及有效性。First of all, the standard of STEP-NC was introduced and the advantages of using XML to express informa- tion in STEP-NC program were presented. And then a proper XML-based STEP NC interpreter framework was proposed and the STEP NC interpreter was expatiated in details from interpreting the STEP-NC data, generating the tool path ac cordingly, displaying the 3D information. Finally, the system was developed through Visual C＋＋ and the effectiveness of the software was demonstrated by a corresponding milling part example.
