The tool path can be adapted according to the shape of surfaces meanwhile the break , gap and overlap between adjacent surface patches are eliminated 该算法将加工曲面离散成三角化模型,在三角化模型中直接生成无干涉刀位轨迹,刀轨生成与刀轨干涉处理统一在一个演算法中。
After a series of operations on the surface model built from measured data points , the continuity along the common boundary or around the corner region of some adjacent surfaces may be destroyed 基于散乱点重构出来的b样条曲面模型在经过一系列的后序编辑工作之后,相邻曲面在公共的边界处或角点区域处的连续性往往会被破坏。
Once a region of the line drawing and a surface of the planar object are homographs , the adjacent surfaces are following to be analyzed . repeat this processing until all surfaces of the planar object have been examined 任何平面立体都是若干个平面多边形围成的,平面多边形的特性能惟一确定平面立体的特性,通过对平面多边形的识别可以达到对整个平面立体的识别。
