Monitoring technologies have attracted attention in the factory automation fields that rely on the Internet of Things (IoT). However, it is difficult to monitor the process information from a round machining tool during rotating operations. Therefore, we developed a novel tool holder equipped with a wireless communication function to monitor tool vibrations. In the present study, we attempt to measure the tool holder vibrations during ball nose end milling processes using the servo driving information for different machine tools. We demonstrate that, using the developed tool holder with a wireless system, it is feasible to improve the machined free form surface by considering the servo driving information.
