Chatter vibration can be monitored by using external sensors such as acceleration sensors and dynamometers. However, from the viewpoint of reliability, using external sensors leads to an increase in failure rate. Therefore, we developed a disturbance observer theory-based method for the detection of chatter vibration, and confirmed its validity experimentally. The developed method does not require the use external sensors. In this study, a system for the in-process suppression of chatter vibration is developed by applying the abovementioned detection method. In a milling test, conducted to verify the developed system, it was found that chatter vibration was successfully suppressed by automatic adjustments to the cutting conditions.
