This research project is a knowledge transfer based on the research project "Modellierung und Simulation des NC-Formschleifens zur gezielten Erzeugung von Werkstückoberflächen unter Berücksichtigung der Werkzeugtopographie und des Werkzeugverschleißes". Based on the results obtained so far, a previously developed geometric physically-based process simulation for NC grinding processes with electroplated diamond tools will be extended in order to design dental instruments which are used in hand-guided machining operations. In this transfer project, the knowledge gained so far will be transferred prototypically to new tool concepts. The research will be carried out in cooperation between the Chair XIV - Virtual Machining at TU Dortmund University and the Gebr. Brasseler GmbH & Co. KG. The central objective of the project is the further development of the simulation system for the design of dental grinding tools and the optimization of hand-guided processes. For validation, prototypical grinding tools will be designed, manufactured and analyzed. Based on the previous findings and the simulation model developed in the previous research project, the transfer to an industrial application will be achieved by specifically designing and optimizing dental instruments. The dental application is a hand-guided and therefore force-controlled process, requiring extensive investigations and significant extensions of the simulation system in this transfer project. By developing a mobile analogy test unit, the tool movements and process forces occurring during hand-guided machining will first be analyzed experimentally. In an analogy test setup, which will be developed in this project, the application behavior of the tools will then be analyzed, especially with regard to tool wear. The knowledge gained will serve as a basis for the further development of the process simulation. The focus is on the development and testing of a corresponding design methodology for optimizing the efficiency and service life of dental grinding tools by designing appropriate tool topographies and process configurations in cooperation with the application partner.

该研究项目是基于“NC-Formschleifens zur gezielten Erzeugung von Werkstückoberflächen unter Berücksichtigung der Werkzeugtopographie und des Werkzeugverschleißes”研究项目的知识转移。根据迄今为止获得的结果，先前开发的基于几何物理的工艺模拟将使用电镀金刚石工具进行数控磨削工艺，以设计用于手动引导加工操作的牙科器械。在这个转移项目中，迄今为止获得的知识将被原型转移到新的工具概念。该研究将由多特蒙德工业大学虚拟加工主席 XIV 和 Gebr 合作进行。布拉塞尔有限公司两合公司。该项目的中心目标是进一步开发用于牙科磨削工具设计和手动引导流程优化的模拟系统。为了进行验证，将设计、制造和分析原型磨削工具。基于之前的研究结果和之前研究项目中开发的仿真模型，将通过专门设计和优化牙科器械来实现向工业应用的转移。牙科应用是一个手动引导的过程，因此是力控制的过程，需要对该转移项目中的模拟系统进行广泛的研究和重大扩展。通过开发移动类比测试单元，将首先对手动引导加工过程中发生的刀具运动和加工力进行实验分析。在本项目将开发的类比测试设置中，将分析工具的应用行为，特别是工具磨损方面的行为。获得的知识将作为进一步开发过程模拟的基础。重点是开发和测试相应的设计方法，通过与应用合作伙伴合作设计适当的工具拓扑和工艺配置来优化牙科磨削工具的效率和使用寿命。
