摘　　要：从实际生产经验出发,探索了提高材料利用率的方法。通过对矩形和异形铺叠料片算法分析,制定了最佳放置策略规则。通过对蒙皮余量的修改工艺性验证后,对余量设置提供了参考依据,创造性地提出了通用零件余量设定原则,减少由于余量设置不精确造成的浪费。通过套裁方案的实施,切实有效地减少了材料的浪费,提高了原材料的利用率。Based on the practical production experience, this paper explores the methods to improve the utilization rate of materials. Based on the analysis of the algorithm of the rectangle and the special shape, the rule of the best placement strategy is established. After the verification of the modification process of the skin allowance, the reference basis for the allowance setting is provided, and the general part allowance setting principle is creatively proposed. Waste is reduced due to imprecise margin setting. Through the implementation of the program, the waste of materials is effectively reduced and the utilization rate of raw materials is improved.
