摘　　要：针对某船用柴油机关键件的结构特点,在数字化模型基础上,基于模块化思想,采用成组技术,分析各加工部位的特点,提取其特征信息和工艺信息,生成待加工区域的刀具轨迹。根据实际加工机床的特点,将刀具轨迹后置处理为实际的数控程序。相关信息按照特征相似性分级保存在数据库中,方便在CAD/CAPP/CAM过程中进行无缝传递。基于NX平台开发集成系统,并使用软件和实际机床进行了验证实验。系统操作简单,交互性好,并且便于扩展应用到其他类似的零件。Based on modularization, the feature information and process information on the working regions of the key parts of a certain marine diesel engine are extracted from CAD models by adopting th~ group technology for tool path generation. Then the tool paths are processed to produce practical NC programs on the basis of NC machining charac- teristics. The two types of information are categorized and saved in a database according to their feature similarity, so that they can be seamlessly transferred with the above-mentioned processing procedures. Finally, a CAD/CAPP/CAM （Computer Aided Design/ Computer Aided Process Planning/Computer Aided Manufacturing） integrated the key parts of the marine diesel engine is developed with NX secondary development. The integrated applied to and validated by a real case through software simulation and real NC machining. It has ease for sound interaction and can be applied to the integration of information on other complicated parts. system for system is operation,
