Representation and Triangulation for Trimmed Parametric Surface
【摘要】 本文提出的参数trimmed曲面的表达模型,包括了几何造型和NC加工所需的信息,有利于复杂组合曲面CAD/CAM的集成.此外,还提出了一种基于窄多变形带的新的trimmed曲面三角化算法.
【Abstract】 This paper presents the model of trimmed parametric surface.The model consists of the modeling and NC machining information of trimmed surface,and can he used in the CAD/CAM integration for compound curve surface. Meanwhile,a new approach to triangulation algorithm for trimmed surface is presented by The authors. The main idea is based on constructing narrow polygons around trimming curves. The algorithm consists of:(1) Reconstruction of intersection curve of surfaces,(2)Adaptive subdivision of surface;(3) Construction of narrow polygon zone;(4)Triangulation of narrow polyrgon zone;(5) Reconstruction of technology relation.
