项目摘要

The properties of metallic bonded grinding wheels depend on the properties of the grinding grains as well as the components of the binding system and the process parameters during the manufacturing process (sintering process) of the grinding tool. All these properties together determine the performance of the tool. The knowledge of the correlations between the manufacturing of the grinding wheel, the adjusted properties by the manufacturing and the resulting performance is currently not available for scientists. Usually research institutes are provided with grinding tools with the required properties (e.g. hardness) by the manufacturing company. However, due to this procedure it is not possible to correlate the process performance with the manufacturing process of the tools. For this reason, there is currently only limited understanding on the whole process chain for grinding with bonded grinding wheels. Furthermore, the adjustment of the properties, e.g. hardness of the bonding, is done by applying additives. This makes it difficult to identify higher-level relations and general conclusions on the grinding process and the dressing process as well. For cutting processes research on the influence of the tool manufacturing on the tool performance is carried out since many years. This made it possible to adjust the tool properties on the process. The aim of this research project is to close the described knowledge gap for grinding tools. The focus is on the determination, how the sintering process determines the tool properties and which of the tool properties are relevant for the process performance.

金属结合剂砂轮的性能取决于磨粒的性能以及结合剂系统的成分和磨具制造过程（烧结过程）中的工艺参数。所有这些特性共同决定了工具的性能。目前科学家还没有掌握砂轮制造、制造过程中调整的性能和最终性能之间的相关性。通常研究机构由制造公司提供具有所需特性（例如硬度）的磨削工具。然而，由于该过程，不可能将过程性能与工具的制造过程相关联。因此，目前对粘结砂轮磨削的整个工艺链的了解有限。此外，通过施加添加剂来调节性能，例如粘合的硬度。这使得很难确定更高层次的关系和一般结论的磨削过程和修整过程以及。对于切削加工，多年来一直在研究刀具制造对刀具性能的影响。这使得可以在过程中调整工具属性。本研究项目的目的是缩小所描述的磨削工具的知识差距。重点是确定，烧结过程如何确定工具属性，以及哪些工具属性与过程性能相关。
