摘要
提出复合条带三阶段排样方式用以解决无约束二维剪切排样问题。该排样方式用3个阶段将板材切割成毛坯,首先用水平刀具将板材切成复合条带,然后用竖直刀具将复合条带切成初始毛坯,最后用水平刀具将初始毛坯切成具有精确尺寸的毛坯。采用背包算法生成该种排样方式,该算法求解两个背包模型分别生成条带在板材中的布局和毛坯在复合条带中的布局。采用文献中基准测题,将文中排样方式与文献中5种重要的排样方式进行比较。实验结果表明,文中复合条带三阶段排样方式平均排样价值高于以上5种排样方式,且切割工艺比较简单。
The three-stage nesting patterns for composite strip were proposed to solve the unconstrained two-dimensional nesting problem.Plate was cut into rectangular blanks through three stages. Firstly,the plate was cut into composite strips by the horizontal cutter,then it was cut into initial blanks by the vertical cutter. Finally,the initial blank was cut into exact size blank by the horizontal cutter. The threestage nesting patterns for composite strip were generated by Knapsack algorithm,which solved two knapsack models to generate the layout of strips in plate and blanks in strip. The patterns were tested through benchmark problems in literature,and compared with five important patterns in literature. The experimental results show that the average value of three-stage nesting patters for composite strip is higher than that of the above five patterns,and the cutting process is relatively simple.
