摘要：

针对圆形件下料问题，从条带的利用率角度讨论了板材上圆形件的排样问题。条带上圆形件的排样一般有3种排法：并排、品排和基于品排的斜排。由于基于品排的斜排极大地减小了相邻圆形件之间和板材边界与圆形件之间的空隙，因此被认为是最好的排样法。从理论分析、数据模拟和实例计算3个方面出发，具体分析了上述3种排法的优劣，旨在得出已知毛坯规格及数量时，采用何种排样方式排入毛坯。结果显示：基于品排的斜排在绝大多数情况下，材料利用率都优于其他两种方法，且3排斜排优于2排斜排；但从实际角度出发，当某块板材排入的需求毛坯数不大于10时，应采用并排法排入毛坯，当需求毛坯数大于10时，应采用3排品排法排入毛坯。

For the cutting problem of circle pieces, the layout problem of circle pieces on a sheet was discussed from the aspect of strip utilization, and there were three methods of layout for circle pieces on a strip, such as parallel arrangement, interlaced arrangement and oblique arrangement based on interlaced arrangement. However, the oblique arrangement based on interlaced arrangement was considered to be the best method due to reducing the space between adjacent circle pieces and between the boundaries of sheet and circle pieces. Based on theoretical analysis, data simulation and example calculation, the advantages and disadvantages of the above three methods were analyzed in order to lay out by the suitable method when the specifications and quantities of blanks were known. The results show that under the most conditions, the material utilization of the oblique arrangement based on interlaced arrangement is better than that of the other two methods, and the three-row oblique arrangement is better than the tworow oblique arrangement. But for practical reasons, the parallel arrangement is optimal when the required blank number of layout on a sheet is not more than 10, otherwise the threerow interlaced arrangement is optimal.
