| 摘 要： | 提出了一种基于特征的模具参数化设计方法。装配关系和模具零件由特征描述，特征间的相互联系则由父子关系结构来描述。通过设计参数来修改特征形状和定位，并采用专家系统驱动满足给定约束条件的特征几何形状。该方法提供了一种更加自然和方便的表示模具参数化模型的途径。

| Abstract: | An approach to feature-based parametric design for die and mould is proposed in this paper.The assembly relationship and parts of the die and mould are described by feature.The dependent relationship of features is described by parent-child operator structure.The feature shape and location can be modified by design parameters.An expert system is used for deriving a geometry of the features which satisfies the given constraints.This approach provides a more natural and convenient method of representing a parametric model of the die and mould. |
