Research And Application Of The Cutting Stock System For Project Manufacture Enterprises

The manufacturing system is the system that continuously converts manufacturing resource to products. It turns out products and creates wealth , at the same time, it consumes vast resource. There exists serious waste of resource in the mass and extensive manufacturing system. So the research on optimal utilization technology of manufacturing resource is of great significance to improve the utility of manufacturing resource, to reduce resource consumption and thereby to improve the whole benefit of manufacturing. From the aspect of system integration, this paper has a deep research on the material resource consumption in the Project Manufacture Enterprises. And this paper also deeply studies the cutting-stock technology that has notably influence on the utility of material resource in the design stage.Firstly, this paper analyzes the characteristic of single piece and the mass material resource consumption in the Project Manufacture Enterprises, and the characteristic of large numbers of stock resource consumption in which, general plan of the Cutting stock System for Project Manufacture Enterprises is proposed. On the base of the general plan, this paper brings forward the system structure of the cutting stock system, and analyzes the function, input and output, working flow of each module in detail.Then, this paper deeply studies the key technology of the Cutting stock System for Project Manufacture Enterprises: optimized cutting stock, graph disposal and system integration, etc. After analyzing the working flow of the column generation technology, brings forward the interpolation algorithm for solving Non-Guillotine Cutting stock problem. Image processing technologies including parts image processing and result image generating are studied. A academic and technological proposal is provided to enable the closely integration between cutting stock technology and CAD, CAPP, CAM, on the base of integration technology. The product developed on the basis of some achievements in this paper is extended and applied in dozens of enterprises. And the applications have got content result in reducing the material consumption and improving the design level.
