面向制造设计(DFM)的特征造型系统的研究

Development of Feature Modelling System Based on Design for Manufacturing

在研究面向制造设计的特征造型系统特点的基础上，以回转类零件为对象，开发了一个基于特征的三维实体造型系统。用一种实用的特征分类与表达方法和在特征造型过程中一种新的信息建模方法，解决了面向制造设计所涉及的各阶段数据共享问题。该系统的开放性结构使之能方便移植和扩展。

A feature modellign system for rotational parts is developed based on DFM(desing for manufacturing).A practical method of feature classification and expression and a new information model of feature modelling are proposed to achieve shared data during DFM processes.This system has an open structure,so it is reconstructed conveniently.
