We have developed a novel wireless multifunctional tool holder system to monitor the process vibrations of a rotating machining tool. The primary feature of the developed holder system is its ability to detect vibrations in three directions, two of which lie along the orthogonal axes, with the remaining direction of detection occurring along the rotational axis. This study aims to evaluate the vibrations induced by tapping and end-milling processes. It is demonstrated that the developed holder system enables the stick-slip vibrations induced by tapping and the chatter vibrations of end-milling to be monitored. Consequently, the developed holder system is found to be effective at estimating and improving the machining conditions that use a machining center.
