【摘要】 目前，国际化市场竞争越来越激烈，使我国相当多的制造企业遇到了前所未有的挑战。为了摆脱这一困境，运用现代信息技术改造和提升制造业，将信息化和工业化结合，是符合我国制造业国情的一条发展之路；在制造类企业中，数控技术为制造技术发展和进步开辟了极为广阔的天地，在实现CIMS中扮演了极为重要的角色。因此，如何提高数控加工效率成为现今研究的一个热点。 本文结合国防科工委“高效数控加工技术研究—成飞示范工程”课题中单元化制造资源管理系统的研究与应用，从车间层开始围绕制造资源计划(MRP Ⅱ)和准时制生产(Just In Time，简称JIT)的需求并结合制造执行系统(Manufacturing Execution System)的特点对车间资源的管理作了一定的研究和探讨，并付诸实践，以适应先进的管理理念；实现了成飞数控加工中心刀具、量具、工装、物料等制造资源的计算机辅助管理，介绍了一些计划与调度管理、库存管理、成本管理的管理思想、理念及方法，完成了与车间生产调度部门、工艺部门、经营管理部门的信息共享和集成，从制造资源的角度保证了成飞数控加工中心的生产能有序、受控的进行；对今后的车间层制造资源管理探索出了一条切实可行的解决途径。 本文以刀具管理为例，研究了高效数控环境下制造资源管理的现实需求及主要的工作流程；采用IDEFO、IDEF1X方法建立了系统的功能模型和信息模型；并在车间局域网的支持下，采用联合应用开发(JAD)方法(即程序开发人员与最终用户共同开发系统)，以先进的管理理论为指导，结合生产现场的实际情况，利用成熟的软件开发工具开发了C／S模式下的计算机辅助制造资源管理系统软件。 通过单元化资源管理系统的应用，使成飞数控加工中心的制造资源管理上了一个新台阶，数控加工效率得到很大提高，完成了国防科工委“高效数控加工技术研究”课题对此部分要求。更多还原

【Abstract】 Now, the competition in internationalization market is more and more vigorous, and makes lots of manufacturing business enterprise of our country meet the unprecedented challenge. To get away from this predicament, to reform and promote manufacturing industry with modern information technique, and to combine information technique and industrialization is the road of a development that accords with the national conditions of our country; The technology of numerical control has opened up the very vast universe for the development and advancement of manufacturing enterprise automation and manufacturing technical, and has acted very important role in CIMS. How to raise the machining efficiency of numerical control is becoming a hot point that is studied nowadays.This paper combines the application and research of cellular manufacturing resource management system in high-efficient numerical control machining technique research of COMMISSION OF SCIENCE TECHNOLOGY AND INDUSTRY FOR NATIONAL DEFENSE and demonstration project research of CHENGDU AEROCRAFT CORPORATION, studies and practice the management of workshop’s resource management which according to MRP Hand JIT ’s thoughts and the characteristic of Manufacturing Execution System to meet advanced management concept; Have realized the computer-assisted management of the measuring tool, cutter, fixture and material in NUMERICAL CONTROL MANUFACTURING CENTER of CHENGDU AEROCRAFT CORPORATION, Have introduced some manage method, concept and the management thought in Production Planning and Controlling management, stock management and cost management; Makes the information of cost manage department, technology department and resource management department can be shared and integrated with each other, have guaranteed the production of NUMERICAL CONTROL MANUFACTURING CENTER of CHENGDU AEROCRAFT CORPORATION can go on by order;This paper is taking the management of cutter as a sample, have studied the major working process and the realistic demand of resource management in the environment of numerical control; Have established systematic function model and information model with the method of IDEFO, IDEF1X; Under the support of intranet, with the method of joint application and development, combines advanced management theory and reality, using mature software development tool, this paper have developed the computer-aided manufacturing resource management software under the pattern of C/S.Through the application of resource management system, the manufacturing resource management of NUMERICAL CONTROL MANUFACTURING CENTER of CHENGDU AEROPLANE CORPORATION has gone up a new step, and the numerical control machining efficiency has got great raising. This study completes partial program of "the research of high-efficient numerical control machining technique" for COMMISSION OF SCIENCE TECHNOLOGY AND INDUSTRY FOR NATIONAL DEFENSE.更多还原
