【摘要】：生产准备工作是联系产品设计和产品制造的桥梁,其过程涵盖了毛坯、工艺、工装、设备等准备工作及工艺信息组织管理,其准备过程及水平直接影响了生产周期和制造成本。目前,大多数的企业都是利用计算机辅助技术,关注于企业的信息化技术的运用,使得工艺编制及管理手段的进一步加强与提高,因此对生产准备过程及结果提出了更高的要求;而对工艺任务的资源分配和工艺任务管理等这类生产准备工作关注较少,使其逐渐成为工艺设计过程中的瓶颈问题。针对这一问题,本文分析了工艺资源在企业中应用的情况,对资源进行需求分析,建立了工艺资源的关系模型;在此基础上,依据工艺资源、工艺子任务和加工方法之间的映射关系,给出了分级规划的策略;通过建立了工艺资源的分配模型和资源分配的评价体系,对工艺资源的分配方案作出评价,得到优化的工艺资源分配方案;最后结合以上的工作和研究的成果,设计并开发了生产准备信息系统,可以直接指导企业的生产准备工作。通过构建以工艺任务为应用对象,结合当前企业的信息化发展的现状,站在资源的高度,以计算机辅助工艺过程设计系统为依托,构建一个以统一资源为基础的生产准备管理平台,它可以减轻工艺设计人员的复杂、重复的工艺设计工作,减少生产准备的周期,提供优化的工艺资源分配方案,为企业的信息化发展奠定良好的基础。
[Abstract]:Production preparation is a bridge between product design and product manufacturing. The process covers the preparation of blank, process, tooling, equipment and process information organization and management, and its preparation process and level directly affect the production cycle and manufacturing costs. At present, most enterprises use computer aided technology, pay attention to the application of enterprise information technology, so that the process planning and management means are further strengthened and improved. Therefore, higher requirements are put forward for the production preparation process and results, but less attention is paid to such production preparation work as resource allocation and process task management, which makes it gradually become the bottleneck problem in the process planning process. In order to solve this problem, this paper analyzes the application of process resources in enterprises, analyzes the requirements of process resources, and establishes a relational model of process resources. The mapping relationship between process sub-task and processing method is given, and the strategy of hierarchical planning is given, the allocation model of process resource and the evaluation system of resource allocation are established to evaluate the allocation scheme of process resource. Finally, a production preparation information system is designed and developed based on the above work and research results, which can direct the production preparation work of the enterprise. Through constructing the process task as the application object, combining the current situation of the enterprise information development, standing at the height of the resources, relying on the computer aided process planning system, A production preparation management platform based on unified resources is constructed, which can reduce the complexity and repetition of process planning, reduce the cycle of production preparation, and provide an optimized process resource allocation scheme. For the enterprise information development laid a good foundation.
