摘要
特征设计是当前解决CAD/CAM集成的重要方法之一.但目前特征的描述及特征建模的方法还不能解决CAD/CAM集成过程中提出的问题.这些问题包括特征库中特征类的简化、特征灵活性与变化性,设计特征映射成加工特征的困难等等.现提出一种特征约束建模的方法,能较好地解决上述问题,并给出基于这种建模的CAD系统的结构.
Feature design is an important method to deal with the CAD/CAM integration at present. However, with the present method of feature description and feature modeling, the problems such as the feature class simplification, the feature adaptability and variability, the difficulties of mapping between design feature and machining feature met during CAD/CAM integration can't be properly solved. A method, the feature constrained modeling method, in order to solve the problems mentioned is presented. The structure of the CAD system for the modeling is given.
