CAD/CAM 集成环境下的基于特征设计方法

Feature-based design methodology under the environment of CAD/CAM integration

本文从三个方面研究了ＣＡＤ／ＣＡＭ集成环境下的基于特征设计方法：形式化定义，设计过程模型，设计算法及其系统结构。文中给出了特征定义、特征操作、特征模型验证及特征映射策略及其形式化描述方式，建立了面向ＣＡＤ／ＣＡＭ集成的基于特征设计过程模型，并提出了基于特征的设计算法及相应的系统基本结构。

This paper studied the feature-based design methodology under the environment of CAD/CAM integration in three aspects:formalized definition,model of design process,design algorithm and its systematic structure.In this paper the feature definition,feature operation,verification of feature model,strategy of feature mapping and its formalized descriptive modality are presented and the process model of feature-based design facing the integration of CAD/CAM is established.Finally it put forward the feature-based designing algorithm and the related basic structure of this system.
