【摘要】 制造系统是将制造资源不断转换成产品的系统。制造系统在不断生产产品、创造财富的同时，也消耗了大量的资源。在量大面广的制造系统中，制造资源的浪费情况严重，进行制造系统的资源优化利用技术研究，对提高制造业资源利用率，降低资源消耗，从而提高制造业整体效益具有重要意义。本文从系统集成的角度对工程项目型制造企业板材物料资源的消耗进行了较深入的研究，同时深入研究了设计环节中对板材物料资源的利用效率有显著影响的优化下料技术。首先分析了工程项目型制造企业的单件性、物料消耗大的特征，和其板材物料资源消耗量大、周期长的特点，提出了面向工程项目型制造企业的板材下料系统的总体方案。针对该总体方案进行了板材下料系统的系统结构设计，并对各个模块的功能、输入输出、处理流程进行了详细的分析。然后针对面向工程项目型制造企业板材下料系统涉及的优化下料、图形处理、系统集成等关键技术进行了较深入研究。分析了优化下料算法——列生成法的求解流程，提出了插补求解二维Non-Guillotine 切割的启发式算法；分析了图形处理技术，包括零件图预处理技术和结果图生成技术；提出了系统集成的方案，实现了优化下料技术与CAD、CAPP、CAM技术的有机集成。基于本文的研究成果开发的产品——钣金下料系统软件，在企业进行了实际应用。在减少物料资源消耗、提高企业的设计水平方面，取得了较好的应用效果。更多还原

【Abstract】 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.更多还原
