Study on Feature-baseded Modeling System for Rotational Parts

本文通过对回转体类机械零件进行特征分类与体素定义、设计及操作生成零件的几何模型和特征模型．并提出了一个基于特征表达的回转体类机械零件几何模型及数据结构，并对回转体类零件的特征信息表达及表达的数据结构进行了尝试．

It has here reconized that feature-based modeling system can provide high-level abstraction of parts that relates directly to certain design functionalities and manufacturing characteristics, A feature-based modeling system for rotational parts is proposed The paperdescribes the definition and design of the feature of rotational parts. A geometric model based on feature and a feature model are designed and implemented.
