This project of the research unit FOR1845 focusses on the development of a position control for rotating diamond tools on the basis of thermal expansion of the tool holder. Due to required nanometer precision - the cutting edges need to be aligned within the same order of magnitude as the kinematic roughness of the surface - this can only be achieved by a dedicated feedback loop and a sophisticated control of the required heat source.
