文摘

The volumetric composition of a grinding wheel is decisive for its structure and topography properties. However, the application-specific choice of grinding wheels is commonly based on experience. To enable a knowledge-based selection of grinding wheels, the WZL and the IGPM of the RWTH Aachen University develop a mathematical model in order to simulate the structure and the topography of a grinding wheel dependent on its volumetric composition. This paper presents a numerical model, which allows the simulation and display of the grinding wheel structure depending on its volumetric composition. Thereby, the grain morphology, the grain size distribution as well as pores and different bonding types are considered. Furthermore, a method to verify the results of the model is introduced and the correlation between the simulation and the real grinding wheel structure is shown.
