摘要
针对最小矩形包络算法处理不规则多边形时包络率低并造成板材使用率低的现象,在最小矩形包络算法基础上,提出三角形处理法。通过包络求解、分类、组合三个环节将不规则凸多边形转化成矩形,并采用遗传算法及最低水平轮廓算法进行矩形排样。通过对比实验,验证了三角形处理算法提高板材使用率的有效性。
When dealing with irregular polygons,the smallest rectangle envelope algorithm has low envelopment rate,this causes low sheet utilisation rate. To solve the problem,this paper puts forward the triangular processing algorithm based on the smallest rectangle envelope method,it converts irregular convex polygon into a rectangle through three links of envelope calculation,classification and composition. Moreover,it uses genetic algorithm and minimum-level horizontal contour algorithm to operate rectangular layout. Contrast experimental results verify the effectiveness of the proposed algorithm in increasing the sheet utilisation rate.
