Intelligent layout method used for rectangular part

Abstract

The invention discloses an intelligent layout method used for a rectangular part. The method comprises the steps that S1 relative parameters of the genetic algorithm are initialized; S2 relative information of the rectangular part is extracted from a rectangular part bank to be laid out; S3 relative information of raw material boards is extracted from a board tank; S4 the obtained information is coded, and primary species are generated randomly; S5 one-by-one decoding is conducted on the primary species by means of the lowest horizontal line search algorithm to obtain solution using efficiency; S6 selection, crossover and mutation operation is conducted according to the genetic algorithm until iteration is finished, and the optimal layout scheme is output. According to the intelligent layout method, the process requirement of the rectangular part can be met well, the intelligent algorithm and the heuristic algorithm are combined, one optimizing scheme can be found rapidly and efficiently, and therefore the material using rate of an enterprise is greatly improved, layout time can be obviously shortened, and layout efficiency is improved.

Description

Technical field [0001] The invention belongs to the field of layout of processed parts, and in particular relates to an intelligent layout method for rectangular parts. Background technique [0002] The nesting problem is a problem commonly encountered in the production practice of metal manufacturing, papermaking, glass manufacturing, furniture manufacturing, automobile manufacturing and other manufacturing fields. An effective nesting method can enable companies to perform the best The required parts are cut, which can greatly improve the utilization rate of raw materials and cutting efficiency, thereby improving the economic benefits of the enterprise. [0003] The traditional layout method mostly uses manual layout and blanking, and the operator simply arranges and cuts the material on the raw material board according to the size and quantity of the parts. This traditional production method of manual nesting and blanking is prone to cause a large amount of leftover materials, ...

AI Technical Summary

Problems solved by technology

This traditional manual layout and blanking production method is likely to cause a large amount of leftover material, and the company cannot achieve the layout budget

[0004] For the layout optimization of rectangular parts, the existing optimal layout methods often do not consider the special process of rectangular parts, the fiber direction, and "one size fits all" (the so-called one size fits all refers to the cutting equipment of rectangular parts such as sawing machines and shearing machines. Machines, etc. can only cut along a certain direction during processing until the cutting is completed), so it is not suitable for "one size fits all" layout optimization of rectangular parts

Manual layout of rectangular parts is inefficient and the layout effect is not ideal. Therefore, how to customize the processing requirements of rectangular parts according to the specific process requirements of the rectangle and its own characteristics can make more effective use of raw materials and greatly A nesting method that reduces production costs and is more efficient has become an urgent technical requirement in the industry
