面向设计与制造的曲面数据模型

Sculptured Surface Data Model for Design and Manufacture

讨论曲面零件信息建模方法 ,通过建立信息处理、转换模块以连接CAD/CAM .中间数据模型提供了连接不同视域、不同层次特征的中间机制 .通过建立中间数据模型 ,设计者可以交互拾取面体素来定义一个待评估的特征区域 ,并通过形式化属性的赋值转化中间数据模型为特征模型 ,实现连接不同抽象层次特征的特征转换 .

The information modeling of sculptured surface is discussed. An information processing and converting module are developed in order to integrate CAD and CAM. A data model, named “InterData”, provides intermediate mechanism to connect different fields and features levels. By the use of “InterData” model, designers can define an evaluated feature area by interactively picking up a surface entity, and “InterData” model can be converted to feature model by assigning values to formalization attributes. The features of different abstract levels can be converted.
