摘　　要：文中提出了一种基于STEP-NC的数控铣削加工系统,构建了系统的结构体系,研究了在VC++6.0环境下,应用SAX接口,通过检索和处理XML文件信息来建立STEP-NC铣削解释器。应用解释器提供的各种特征信息,刀轨生成器运用类似旅行商问题的遗传算法对路径进行优化,最终实现STEP-NC铣削系统刀具轨迹的自动生成。最后通过实际加工来验证所生成的刀具轨迹是符合加工要求的。A Milling system based on STEP-NC is constructed in this paper, then the paper introduces the structure of the system, and studys the method of using SAX by searching and disposing the XML file message to develop the STEP-NC Milling interpreter in the environment of VC ＋＋6.0. On the basis of data source from interpreter and parameter and tool database, the tool path generator which is used to implement the automatic generation of tool path in the STEP-NC Milling system is developed. Finally, the actual machining processing is used to check up whether the tool path that generated meets the machining requirement.
