Abstract: An ultrasonic cutter detection method and device, the method comprises the following steps: preliminary detection: frequency amplitude detection and fall-of-potential detection, if the ultrasonic cutter fails the above two detection solutions in the preliminary detection, repeating the two detections; if the ultrasonic cutter still fails the above two detection solutions, the ultrasonic cutter is judged to be unqualified; and reinspection: free modal detection and pressure modal detection. Using differences of the ultrasonic cutters surface in micro-crack directions that result in different degrees of sensitivity of crack to different ultrasonic vibration modes, combined with the fall-of-potential method and frequency amplitude detection method, a detection rate and a detection velocity of an unqualified ultrasonic cutter can be improved.
