基于黄金分割法的二次加工区域搜索算法研究

Freeform surface with large curvature radius variation，the golden section method is proposed to detect secondary operation regions of freeform surfaces. The three points arc approximating method was used to approximately compute the curvature radius to judge the secondary operation region. The algorithm significantly reduces computing time and improves the search efficiency. By the golden section method can accurately detect the overcutting regions. Computer implementation and practical examples are also presented in this paper.
