通过对零件几何偏差及其来源的理解以及对技术产品功能和质量影响的调查，为计划中的研究单位“基于虚拟计算机辅助工程工具的面向过程的公差管理”建立了框架。本研究单位的目的是提供全面的方法和有效的工具，全面管理的几何偏差沿着产品的起源过程中，这是在一个模型工厂进行验证。在此过程中，我们特别注重开发一个程序，以便从产品开发到制造再到计量，涉及几何变化管理的所有部门进行富有成效的合作，这将使公司能够快速指定可制造和可测量的功能公差，从而节省成本并缩短上市时间。在这方面，研究单位的愿景是使产品开发，制造和计量在计算机辅助公差，即密切合作。e.功能公差的联合制定，这是可制造和可测量的。通过实现这种密切的协作，所有与制造相关的产品功能和质量问题的来源都可以在虚拟产品和过程开发的早期阶段得到考虑。因此，可以有效地指定公差，并可以确定优化的检测计划以及稳健的制造和操作窗口，从而能够以低成本制造和测量稳健的产品。由于几何零件偏差是不可避免的，并影响技术产品的功能和质量，因此沿着产品开发过程的几何零件偏差管理对于功能产品的开发至关重要，，符合客户的品质和使用要求，并在国际市场上取得成功。因此，研究单位第二期的重点是特别考虑运作-相关磨损过程中面向过程的公差分配。科学上的挑战是获取磨损信息，将其转化为数学模型，并随后集成到公差分析和优化中。最后，这允许分配符合生产和测试要求的公差，以确保技术产品在整个预期产品寿命内的功能。因此，研究单位的科学发现和可转让的普遍适用的方法为德国经济的成功做出了宝贵的贡献。

The comprehension of geometric part deviations and their sources as well as the investigation of their effects on the function and quality of technical products builds the framework for the planned research unit “process-oriented tolerance management based on virtual computer-aided engineering tools”. The aim of this research unit is the provision of holistic methods and efficient tools for the comprehensive management of geometric deviations along the product origination process, which are to be validated in a model factory. In doing so, a particular focus is set on the development of a procedure for the fruitful cooperation of all departments involved in geometric variations management, from product development, to manufacturing and to metrology, which will enable companies to quickly specify functional tolerances, which are manufacturable and measurable, and consequently to save costs and to reduce the time to market. In this regard, the vision of the research unit is to enable the close collaboration of product development, manufacturing and metrology in computer-aided tolerancing, i. e. the joint formulation of functional tolerances, which are manufacturable and measurable. By enabling this close collaboration, all manufacturing related sources of later problems regarding the product function and quality can be considered already during early phases of virtual product and process development. As a consequence, tolerances can be specified efficiently and optimized inspection plans as well as robust manufacturing and operating windows can be identified, which allows the development of robust products to be manufactured and measured at low costs. Since geometric part deviations are inevitable and affect the function and quality of technical products, their management along the product origination process is essential for the development of functioning products, which conform to the quality and usage requirements of customers and are successful on international markets.The focus of the second funding period of the research unit is therefore particularly on the consideration of operation-related wear during the process-oriented tolerance allocation. The scientific challenge is the acquisition of wear information, its transformation into mathematical models and the subsequent integration into tolerance analysis and optimization. Finally, this allows the assignment of production- and test-compliant tolerances which ensure the functionality of technical products over the entire intended product lifetime. The scientific findings and the transferable generally applicable methods of the research unit thus make a valuable contribution to the success of the German economy.
