Analysis of force-controlled grinding processes with diamond abrasive belts

涂层磨具是磨削工具中销售贡献最大的磨具之一，广泛应用于各种工业领域。磨料带与常规磨料的工作行为和过程相互作用已基本研究和了解。相比之下，具有超磨料的砂带直到现在几乎还没有成为科学研究的主题。金刚石砂带与普通磨料的典型砂带相比，其微观和宏观结构存在显著差异，这对其运行行为有显著影响。在此背景下，本研究项目的主要目标是在力控制、机器人引导的铸铁加工过程中获得金刚石磨粒带微观和宏观机制的新见解。因此，必须对不同刀具规格和工艺参数下的啮合条件、切削和磨损机制进行分析，并开发出砂带形貌的新具体值。最后，设计了一个过程模型，该模型能够预测强制控制金刚石砂带磨削过程的切削行为和工作结果。

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.
