摘要
本文介绍了一个基于特征造型的成组夹具ＣＡＤ／ＣＡＰＰ／ＣＡＭ集成系统，该系统由夹具ＣＡＤ、ＣＡＰＰ和ＮＣ程序自动生成三个分系统组成。按形状和功能进行特征分类，自动生成特征造型数据文件；利用一个专门研制的程序从特征造型数据中提取ＣＡＰＰ输入数据和待加工表面的几何数据；生成零件加工的ＮＣ刀轨是依据来自ＣＡＰＰ模块的零件代码化的加工过程数据和由特征造型数据中提取的零件几何数据。
The GT fixture is a type of adjustable fixtures and it is used for a group of similar parts. This paper introduces an integrated CAD/CAPP/CAM system for GT (Group Technology) fixture based on feature modelling. The system consists of three subsystems for CAD,CAPP and NC programming separately. According to the shapes and functions the fixtures are classified, and the feature modelling data files are generated automatically. A program is designed to extract the CAPP input data and geometry data of a part from its feature modelling data. The NC tool paths of machining are generated on the basis of the coded process planning data (output from CAPP module) and geometry data (extracted from the feature modelling data).
