主模型概念及其在数控加工中的应用

Master Model and its Application in The CAM

主模型概念是并行工程（ＣＥ）中组织产品数据的核心。本文阐述了主模型定义，创建主模型的原则和方法；本文还利用ＵＧ软件，举例介绍了主模型在ＮＣ编程中的应用及与ＮＣ模型的相关特性。

The Master Model concept is essential in concurrent engineering for product data data, the paper describes master model definition, emphasizes the principles and methods of creating master model, then using UG CAD/CAM software, demos master model application on NC , shows associativity with the NC model.
