摘要:
提出一种实现刀具扫描体与曲面矢量求交的有效算法.将扫描体与复杂曲面法矢的求交问题,转化为三角网格与有向线段之间的求交计算.建立此两者求交计算的求交子集,减少以往算法中不必要的求交计算,提高算法的效率.文中同时给出,基于该算法的整体叶轮叶片复杂曲面加工的应用实例.
Abstract:
An effective algorithm is presented here for seeking and realizing the intersection of tool sweep volume with surface vector. The intersection of sweep volume with complicated surface normal is transformed into computation of intersection between triangular mesh and directed line segment. The efficiency of algorithm is enhanced by setting up intersection subset of these two in the previous algorithm. An example is given here to show the application of this algorithm to the complicated surface machining of impeller vanes as a whole.
