Mass Finishing is a widely used technology for surface roughness improvement and edge rounding, applying loose abrasive particles as tools. Nevertheless only few researchers have investigated this technology and findings are limited to results of empirical studies of specific applications. Consequently mass finishing still remains a black box process that strongly relies on the experience of trained workers for process design and control in industrial application. In the current DFG-project Fundamentals of Mass Finishing first steps towards a comprehensive process model are taken. But shape and size of abrasive media have hardly been considered as a factor in past research. Although manufacturers of media offer a large variety of different media geometries. The influence of size and shape of media on surface evolution will be systematically investigated in the proposed research project. Furthermore current process models, considering the media-workpiece contact as well as material removal mechanisms, and the promising discrete element approach for simulating contact intensities that is established by current DFG-project will be enhanced to ensure wider applicability.

质量精加工是一种广泛使用的技术，用于表面粗糙度改进和边缘舍入，将松散的磨料颗粒作为工具。然而，只有很少的研究人员研究了这项技术，发现仅限于特定应用的经验研究结果。因此，质量精加工仍然仍然是一个黑匣子过程，它强烈依赖于训练有素的工人在工业应用中进行过程设计和控制的经验。在当前的DFG项目基础上，朝向综合过程模型的第一步。但是，几乎不认为磨料介质的形状和大小是过去研究的一个因素。尽管媒体制造商提供了各种不同的媒体几何形状。在拟议的研究项目中将系统地研究培养基对表面进化的大小和形状的影响。此外，考虑了当前的过程模型，考虑了媒体工作接触以及物质删除机制，以及有希望的离散元素方法，用于模拟当前DFG项目建立的接触强度，以确保更广泛的适用性。
