Integrated Design and Optimization of Manufacturing Process Chains considering External Manufacturing Processes

拟议转移项目的目的是工业标准化，提高灵活性，并加强已经开发的DTI方法(技术接口设计)，用于集成设计和优化制造工艺链，该方法是在SFB 489中开发的。其目的是减少复杂产品的金属切割企业的时间和成本。需要在工业可用的模型中模拟生产过程之间的技术干扰，以便以较低的工作量执行过程优化。因此，需要对工艺的技术参数与企业的经济目标(如时间和成本)之间的相互作用进行总体描述，而不考虑工艺的类型和目标。在该项目中，这是通过开发一个标准化的、灵活的框架和模块系统以及DTI方法的标准化程序来实现的。基于所描述的动机，贝克休斯生产地下制造工具的制造系统将作为典型的应用场景。该项目是SFB489的C3模块的知识转移，它为昂贵的资本品制造商提供了一个原型。DTI法是一种基于模拟的过程链优化运行规划方法。它代表了对所有制造步骤和工艺参数之间的工件特性的多标准分析，并已在齿轮、曲轴和小齿轮轴的示范生产系统中进行了预先评估。

The aim of the proposed transfer project is the industrial standardization, improvement of flexibility and enhancement of the already developed DTI-method (Design of Technological Interfaces) for integrated design and optimization of manufacturing process chains, developed within the SFB 489. The intention is to reduce time- and costs within enterprises of metal cutting for complex products. There is a requirement to simulate technical interferences between the production processes in an industrially usable model to carry out process optimizations by low effort. Therefore, it is required to describe the interactions of technical parameters of processes and economic objectives (e. g. time and cost) of the enterprise generally, regardless of the type of process as well as of the objectives. Within the Project, this is achieved by the development of a standardized, flexible framework and module system and standardized procedures for the DTI-Method.Based on the described motivation, the manufacturing system of Baker Hughes, to produce underground manufacturing tools, will be used as typical application scenario. The project is a transfer of knowledge from the C3-modul of the SFB 489, which delivers a prototype for the manufacturer of expensive capital goods. The DTI-method has been developed for a simulation-based planning for an optimal operation of process chains. It represents a multi-criteria analysis of work-piece characteristics between all manufacturing steps and process parameters and has been pre-evaluated by within an exemplary production system for gears, crank shafts and pinion shafts.
