The paper describes an effort to develop a prototype smart boring tool supporting agility at the station level by enabling automated tool change and providing an advanced on-line compensation mechanism. The tool utilizes a compensation mechanism powered by a piezoelectric microactuator driven by an advanced controller, compensating for the position error of the boring bar and effectively rejecting cutting force disturbances. Experimental data were used to verify the theoretical and simulation results indicating successful operation of the tool with the bandwidth of up to 500 Hz, providing the tool tip compensation range of 40 μm with a resolution of 0.2 μm.
