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.

倒角、倒圆角、圆角、键槽和孔等制造特征 仅隐式嵌入实体建模表示中。 的 本研究的目的是开发一种能够 从构造实体中提取这样的制造特征 几何（CSG）树，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 侧重于个人特征的研究，主要是为了发展 能够提取和统一大量 第二阶段涉及协调所有不同的 CSG树内的功能，然后支持应用程序使用， 如自动工艺规划和体积近似。
