摘要：

为解决PCB生产设备尺寸的限制问题，提出PCB多工作板尺寸单一下料精确算法。首先采用动态规划算法确定各种工作板尺寸及其所含PCB单元板数，然后采用拼合算法通过隐式枚举的方式生成所含工作板种数不超过一定数值的板材下料方案。控制板材下料方案中的工作板种数有利于简化切割工艺；通过隐式枚举法考察所有拼合情况，可以获取当前限制条件下的下料方案最优解。将本文下料算法分别与文献中的对比算法以及现有下料软件进行比较，实验计算结果表明，本文算法可以在简化切割工艺的同时保证板材利用率。

In order to solve the problem of size limitation of PCB production equipment, an exact algorithm of single cutting for PCB multi-working plate size was proposed. Firstly, the sizes of working plates and the number of PCB units were determined by the dynamic programming algorithm. Then, the cutting scheme of sheet metal with no more than a certain number of working plates was generated by the joining algorithm through implicit enumeration. Furthermore, controlling the number of working plates in the cutting scheme was beneficial to simplify the cutting process, and the optimal solution of cutting scheme under the current restrictive conditions could be obtained by investigating all the splicing conditions by implicit enumeration method. Compared the algorithm with the algorithm in the literature and the existing cutting software respectively，the experimental results show that the algorithm can simplify the cutting process and ensure the utilization ratio of working plate.
