【摘要】 特征造型技术是实现ＣＡＤ／ＣＡＰ／ＣＡＭ集成的关键技术之一，其先进性要求它除了信息完备以外，还应与参数化设计技术有机结合起来，从而实现已建模型的动态修改，提高设计的自动化程度。本文介绍了在一个特征造型系统中参数比设计技术的具体应用与方法。更多还原

【Abstract】 Feature-based modelling is a significant technique used in CAD/CAPP/CAM integration.As an advanced technique, feature-based modelling must realize design automation in a great ex-tent. So, parametrization design, which enables the user to modify design model dynamically, is used in Feature-base modelling system. Some detailed applications and ideas of parametrization design technique in a feature-based modelling system are introduced in this paper.更多还原
