摘要
本文研究船用柴油机几个大型零件ＣＡＤ／ＣＡＰＰ／ＣＡＭ集成的关键技术──基于特征的参数造型。该造型的特点一是基于特征，其几何信息和工艺信息主要从制造要求出发；二是造型为ＣＡＤ／ＣＡＰＰ／ＣＡＭ集成服务．造型的数据文件是集成的关键．它在ＣＡＰＰ中自动生成与工艺卡相对应的工序图．在ＮＣ刀轨生成和加工模拟中是主要的基础数据文件；三是参数化造型．使产品修改直观方便。
he parametric feature modelling,that is the key technology of integrated CAD/CAPP/CAM system for box parts of marine diesel engines. The modelling is based on part feature,its geometry and process information are from the manufacturing requirement. The modelling data file is the key of the integration,and is also an important data file in NC machining module and NC simulating module. The modelling is parametric,and is convenient to part modifying.
