Abstract

The invention relates to a two-dimensional irregular part layout method based on an optimal foraging algorithm. The method comprises the steps of S1, conducting mathematical description on the layoutproblem of two-dimensional irregular parts; S2, establishing constraint conditions needing to be met in the layout optimization process; S3, determining a target to be optimized, and establishing a corresponding two-dimensional irregular part layout target optimization function; and S4, performing global optimization search on the arrangement sequence and the rotation angle of the parts based on an optimal foraging algorithm, determining the optimal arrangement sequence and the rotation angle of the parts, and outputting an optimal layout result. The two-dimensional irregular part layout method based on the optimal foraging algorithm is suitable for layout of convex and concave polygonal parts and complex parts with holes. Compared with a two-dimensional irregular layout problem solving method based on a traditional heuristic algorithm, the method is high in layout efficiency, good in robustness and high in material utilization rate.

Description

technical field [0001] The invention relates to the technical field of computer aided nesting, in particular to a two-dimensional irregular parts nesting method based on an optimal foraging algorithm. Background technique [0002] 1. The layout problem refers to the reasonable layout of the parts to be involved in the layout according to the processing requirements in the given raw material plate space, so as to maximize the utilization rate of raw materials while ensuring the production demand of the product. At present, layout problems are involved in many processing and manufacturing industries. And with the rapid development of society, human demand for resources is also increasing. Saving resources and reducing resource waste as much as possible have become an important pillar of sustainable development in today's society. [0003] 2. For the layout of two-dimensional irregular parts, manual methods were mainly used in the early stage. This method not only cannot save ...
