Research Initiation: Extraction and Unification of Manufacturing Features in Constructive Solid Geometry

诸如倒角、圆角、圆角、键槽和孔等制造特征仅隐式嵌入实体建模表示中。本研究的目的是开发一种能够从构造立体几何（CSG）树中提取此类制造特征的算法，并进一步重建树以统一特征表示。本研究分为两个阶段：第一阶段侧重于单个特征的研究，主要开发能够提取和统一大量特征的算法；阶段2包括协调CSG树中的所有不同特性，然后支持应用程序使用，例如自动过程规划和体积近似。

Manufacturing features such as chamfer, round, fillet, keyway, and bore are only implicitly embedded in solid modeling representations. The objective of this research is to develop an algorithm capable of extracting such manufacturing features from a Constructive Solid Geometry (CSG) tree and further rebuilding the tree to unify feature representations. This research consists of two phases: Phase 1 focuses on the study of individual features mainly to develop algorithms that are capable of extracting and unifying a large variety of features; and Phase 2 involves an effort to coordinate all distinct features within a CSG tree, and then to support application uses such as automatic process planning and volume approximation.
