Research Initiation: Form Feature Recognition Using Convex Decomposition

为了有效地支持各种产品工程应用，需要用更高层次的几何标题来表示产品模型，并从中提取有意义的工程信息。该项目的目标是开发一种基于表单特征的产品模型表示方案。其目的是提供一个产品模型，通过具有适用于广泛制造过程设计活动的内在优势的中心形式特征分解来支持各种产品工程活动。中心形状特征分解是通过使用一种称为分区交替积和的凸分解来自动识别形状特征来获得的。通过利用局部舍入运算，将特征分解所涵盖的产品形状几何域扩展为支持实际零件。所要开发的产品模型方案必须作为产品工程从设计到制造一体化的核心。

To support various product engineering applications efficiently, product models need to be represented with higher- level geometric entitles, from which meaningful engineering information can be extracted. The objective of this project is to develop a representation scheme for product models based on form features. The intent is to provide a product model to support various product engineering activities through a central form feature decomposition that possesses intrinsic advantages applicable to a wide range of manufacturing process design activities. The central form feature decomposition is to be obtained by automatic recognition of form features using a convex decomposition called Alternating Sum of Volumed with Partitioning. Geometric domain of product shapes that the feature decomposition covers is extended to support practical parts by exploiting local rounding operations. The product model scheme to be developed must serve as the core of the integration of product engineering, from design to manufacturing.
