Abstract
A cutting device is provided which can simultaneously achieve a shorter machining time, lower machining resistance during cutting, and high-precision machining. To be specific, the cutting device of the present invention includes a three-axis tool unit including a first actuator operating in a u direction, a second actuator operating in a v direction orthogonal to the u direction, a third actuator operating in a w direction orthogonal to the u direction and the v direction, a tool holder disposed at the intersection of the u direction, the v direction, and the w direction, a tool mounted in the tool holder, and three sensors for measuring the displacements of the first, second, and third actuators, respectively and feeding back displacement signals representing the measured displacements, wherein the first, second, and third actuators of the three-axis tool unit vibrate so as to perform vibration cutting on a work material.
