Simulation-based tool design for hand-guided dental grinding processes with electroplated diamond tools

本研究项目是基于研究项目“Modellierung and Simulation des NC-Formschleifens zur gezielten Erzeugung von WerkstückoberfläChen unter Berück sichtigung der Werkzeugtopatigie und des Werkzeugverschlei？es”的知识转移。在已有研究成果的基础上，我们将对以前开发的基于几何物理的电镀金刚石工具数控磨削加工过程进行扩展，以设计用于手动引导加工的牙科器械。在这个转移项目中，到目前为止获得的知识将典型地转移到新的工具概念上。这项研究将在多特蒙德理工大学第十四教席--虚拟加工与地球科学研究中心的合作下进行。布拉斯勒股份有限公司该项目的中心目标是进一步开发用于设计磨牙工具和优化手动引导过程的模拟系统。为了验证，将设计、制造和分析原型磨具。基于前面的研究结果和前期研究项目中开发的模拟模型，将通过专门设计和优化牙科器械来实现向工业应用的转变。牙科的应用是一个手动引导的过程，因此需要在这个转移项目中对模拟系统进行广泛的研究和显著的扩展。通过开发一种移动式模拟试验装置，首先对手工引导加工过程中的刀具运动和加工力进行了实验分析。在本项目中将开发的模拟测试装置中，然后将分析工具的应用行为，特别是关于工具磨损的行为。所获得的知识将为工艺模拟的进一步发展奠定基础。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图和工艺配置，优化磨牙工具的效率和使用寿命。

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.
