毛坯优化排样是冲压工艺数字化设计中的重要环节, 针对优化排样设计中的各种工程约束, 提出了一种新的求解算法———改进的包络矩形法, 避免了图形加密、等距放大技术带来的计算精度和计算效率不高的问题, 可以完成单排、双排、多排等优化排样方式, 在排样方案修改中, 可通过对步距进行修改, 实现自动排样较难解决的嵌套排样问题。提出了在 I DEAS软件平台上实现毛坯优化排样系统的总体框架, 本系统经实际生产验证, 产生了良好的经济效益。

The optimization of blank layout is of great importance in the design of stamping die. In this paper, according to various engineering constraints during blank layout design, the general frame for blank layout optimization system based on I-DEAS software platform, and a new algorithm, improved enveloped rectangular algorithm was proposed. The improved algorithm solved the problems of low computing accuracy and efficiency of graphic encryption and offset magnification technology. This blank layout optimization system was proved to be able to create good economic returns.
