Abstract
This study tests the dual functionality of a piezoelectric transducer for active control of emulated tool vibration. The concept of a self-sensing actuator is here applied jointly with adaptive feedback active vibration control as hardware-in-the-loop. It controls pre-recorded tangential tool vibrations at the tool holder’s first bending mode. This work shows that the selected building blocks of the complete control loop are key to the design. It opens perspectives for a single transducer design and a simultaneous tool condition monitoring function. 10 dB attenuation of tool vibrations, bending-mode-focussed control command and feedback signal-to-noise-ratio of 20 demonstrate the system’s functionality.
