The objectives of this proposal are based on the work of the first year of research and extend the original research objectives. The overall objective of this research project is to create a grinding wheel model, which is based on the volumetric composition of an abrasive tool. As a result the spatial structure of the components will be depicted realistically. With such a model, it is possible to determine the resulting wheel topography and the mechanical properties of abrasive tools in order to predict their grinding behavior.Starting from the particle volume distribution, the particle size distribution, the grain shapes, the pore volume, as well as the type of bonding and the bonding volume, the volume model is developed. Based on this volume model, the grinding wheel surface can be modeled. The aim is to determine the most important process specific characteristics of the grinding wheel. For this strength properties of the system are take into account, as well as the influence of wear and different dressing and processing conditions.

本提案的目标是基于第一年的研究工作，并扩展了原有的研究目标。本研究项目的总体目标是创建一个砂轮模型，这是基于磨料工具的体积组成。因此，组件的空间结构将被逼真地描绘。从磨粒体积分布、粒度分布、磨粒形状、气孔体积、结合类型和结合体积等方面建立了体积模型，并对模型进行了数值模拟。基于该体积模型，可以对砂轮表面进行建模。目的是确定砂轮最重要的工艺特性。为此，考虑了系统的强度特性，以及磨损和不同修整和加工条件的影响。
