Outline of Final Research Achievements

Suppression of chatter vibration is needed to enhance the machined surface quality and expand tool life. In this study, a new conceptually active approach for chatter suppression in machining is proposed. The hybrid control method developed by applying the sensor-less force control with the disturbance observer enables to simultaneously and independently control position trajectory and band-limited forces. It is introduced to the carriage of the prototype desktop turning machine and the ability to suppress chatter is evaluated by end-face cutting tests. The result shows that actively controlling a band-limited force around a detected vibration frequency leads to avoidance of chatter.
