Abstract: A novel three-dimensional ultrasonic elliptical vibration cutting device, comprising has a two-dimensional ultrasonic vibration transducer, an asymmetric ultrasonic horn, and a cutter. The cutter is installed at the output end of the asymmetric ultrasonic horn, the two-dimensional ultrasonic vibration transducer is used for outputting ultrasonic longitudinal-flexural complex vibration, the asymmetric ultrasonic horn is used for converting and decomposing longitudinal vibration output by the two-dimensional ultrasonic vibration transducer into second-phase flexural vibration and longitudinal vibration, and outputting a three-dimensional ultrasonic elliptical vibration trajectory on the cutter in combination with first-phase flexural vibration output by the two-dimensional ultrasonic vibration transducer. A three-dimensional ultrasonic elliptical vibration trajectory is output in a double-excitation mode. The output three-dimensional ultrasonic elliptical vibration trajectory is adjusted according to different cutting applications and machining requirements so that the device has better adaptability.
