摘　　要：为实现STEP-NC程序的自动生成,开发了STEP-NC程序生成器。首先阐述了程序生成器的工作原理和各个模块的功能及其实现方法。详细论述了程序生成器实现中的三项关键技术。最后,结合一个包含平面、孔和型腔特征的AP203文件,利用所开发的程序生成器生成符合ISO14649标准的完整的STEP-NC程序,并通过STEP-NC铣削仿真系统对所生成的程序进行切削仿真。仿真结果表明,所开发的STEP-NC程序生成器是可行的。To achieve automatic generation of STEP-NC program, an STEP-NC program generator was developed. Firstly, the operating principles of the STEP NC program generator were introduced. According to inner logical relationships, the program generator was consisted of six functional modules, function and realization method for each module were expatiated. Three key technologies of program generation were studied in particular. Finally, exampled with a AP203 file including a planar face, hole, pocket, the whole STEP-NC program was generated based on ISO14649 by the proposed program generator. A cutting simulation was performed on the generated STEP-NC program by STEP-NC milling machining simulation system. Result proved the feasibility and effectiveness of the STEPNC program generator.
