项目摘要

The current state of the research shows increasing requirements to the performance and efficiency of high-alloy stainless steel components with high surface quality and functionalized surfaces. The former can be manufactured by ultra-high precision processing, and the letter by means of micro grinding. As part of this project both, the requirements profile of surface grinding (ultra-high precision processing) and peripheral grinding (micro grinding) will be produced by a single novel procedure. However, up until now there is no knowledge of the boundary conditions of the thin film technology for high quality machining of mono- and multilayer micro grinding tools. At the beginning of the project the manufacturing process will be considered to achieve the defined goal. As regards to the demands made on the micro grinding tools the properties are being evaluated. The grinding tools which are developed and manufactured for the use of micro-abrasiv grinding are examined on the following with regard to their behavior in the use of ultra-precision- and micromachining. The next step is a process modeling concerning behaviors of abrasive layer and support layer. In addition, the removal behavior is described in terms of an empirical model. Based on the manufacture of suitable microstructures the established models are finally validated. Furthermore, the process strategy is considered. Thereby solutions for overcoming limitations of the structure geometry are worked out. Finally, a suited tool manufacturing for the transfer of various application scenarios takes place.

目前的研究状况表明，高合金不锈钢部件的性能和效率要求越来越高，具有高表面质量和功能化表面。前者可通过超高精密加工制造，后者可通过微磨削制造。作为该项目的一部分，表面磨削（超高精密加工）和外围磨削（微磨削）的要求轮廓将通过单一的新工艺产生。然而，到目前为止，人们还不知道薄膜技术在高质量加工单层和多层微磨具方面的边界条件。在项目开始时，将考虑制造过程以实现定义的目标。根据对微磨具的要求，对其性能进行了评价。开发和制造的用于微磨料磨削的磨削工具在使用超精密和微加工时的性能进行了以下检查。下一步是对磨料层和支撑层的行为进行过程建模。此外，根据经验模型描述了去除行为。通过制作合适的微结构，对所建立的模型进行了验证。此外，还考虑了过程策略。从而提出了克服结构几何限制的解决方案。最后，为各种应用场景的转移进行合适的工具制造。
