Simulation-based tool and process design for microfinishing with metal-bonded honing tools

This project is a transfer project which continues the fundamental projects "Experimental and simulation-based fundamental investigations on surface structuring by short and long stroke honing" (BI 498/40-3 and KE 1885/3-3). Building on previous results, investigations are being carried out into the production of rounded contours by microfinishing using new tool concepts, and simulation models are being developed for prototypical process and tool design.  This project is being carried out in cooperation with the Institute of Machining Technology (ISF), the companies NAGEL Maschinen- und Werkzeugfabrik GmbH, ELGAN-Diamantwerkzeuge GmbH & Co. KG as well as Alicona Imaging GmbH and is funded by the German Research Foundation (DFG).

For the simulative analysis of microfinishing, a suitable process model is being developed which, on the one hand, allows precise calculation of the process forces depending on decisive influence parameters such as the use of cooling lubricant and process-specific wear progress and, on the other hand, maps the process-characteristic, force-controlled infeed of the tool. A prognosis and evaluation of tool concept and process parameter values can thus be made, for example, on the basis of the resulting surface topography using defined target variables such as roundness and roughness. The knowledge gained in this way is to be transferred prototypically to industrial application.
