The manufacturing of high-performance carbide tools, like drills or milling cutters, is realized by a grinding process because of the strength and hardness of the used material. Due to the process forces and the cantilevering clamped workpiece, the blank bends and unwanted geometry errors occur. Additionally, great efforts are made to find optimal parameters for stable process conditions. In this work the interaction phenomena of tool grinding process and machine structure are analyzed and modelled. Thereby, the dynamic behaviour of workpiece, grinding wheel, and machine structure is experimentally investigated. Additionally, force signals of the grinding processes are measured and analyzed in time and fi·equency domain.
