| 摘 要： | 特征技术作为ＣＡＤ／ＣＡＭ集成系统的核心技术之一，已经在ＣＡＤ／ＣＡＭ系统集成过程中，充分显示出其优势。但是在目前的特征产品定义模型中，缺少零件加工特征的映射关系，以及ＣＡＤ／ＣＡＭ集成设计的能力，不能满足ＣＩＭＳ环境下的产品设计、制造一体化的要求。本文分析了目前特征基产品定义模型应用于ＣＩＭＳ存在的问题，并针对存在的问题，提出了新的面向ＣＡＤ／ＣＡＭ的宏特征定义方法，并讨论了宏特征的构造和映射关系形式。

| Abstract: | Feature technology is one of the keys of integration CAD/CAM Systems,Feature modeling has displayed their advantages in the integrating process of CAD/CAM. But there are some shortages in the present feature modeling,Such as lack for the parallel design ability and the project relation of process feature.So it is important to build a new feature-based modeling which can design with parallel.This paper analyzes the shortages of present feature- based system and puts forward a new method of feature- based definition- Marco Feature Based Definition.The structure and relation of marco feature project are also discussed in the paper.At last,the CAD/CAM System structure has been described. |
