摘要
制造行业经常采用剪切和冲裁工艺将金属板材切成圆形毛坯.本文提出一种算法,用于生成多尺寸圆形片条带的剪切排样方式.该算法采用剪切工艺简单的多级排样方式,每一刀切下一根水平或竖直的条带,每根条带中可以有一排或多排同尺寸的毛坯.采用递归算法确定每根条带的方向和所含毛坯排数,以便使下料利用率达到最高.实验计算结果表明所述算法在计算时间和提高材料利用率两方面都较有效.
The manufacturing industry often uses the shearing and punching processes to cut the metal sheet into circular blanks. This paper presents an algorithm for generating the strip cutting patterns of circular blanks. It uses the multi-section patterns simple to cut. Each cut produces a horizontal or vertical strip that contains one or more blank rows of equal circles. The algorithm recursively determines for each strip the direction and the number of blank rows included, so thai the material usage can reach maximum. The computational results indicate that the algorithm is efficient both in material usage and in computation time.
