Coated abrasives have one of the highest sales contribution among grinding tools and are used in a broad variety of industrial fields. The operational behavior and the process interaction of abrasive belts with conventional abrasives have essentially been investigated and understood. In contrast, abrasive belts with super-abrasives have hardly been the subject of scientific studies until now. In comparison to typical abrasive belts with conventional abrasives, diamond abrasive belts show substantial differences of the microscopic and macroscopic structure, which has a significant influence on the operational behavior. In this context the main goal of this research project is to obtain new insights into the microscopic and macroscopic mechanisms of diamond abrasive belts during force-controlled, robot-guided processing of cast iron. Therefore, engagement conditions, cutting and wear mechanisms with respect to the different tool specifications and process parameters have to be analyzed and new specific values of the abrasive belt topography have to be developed. Finally a process model will be engineered that enables a forecast of the cutting behavior and work results for a forced controlled diamond abrasive belt grinding process.
