In order to investigate the influence of geometric parameters change of ultrasonic cutting disc cutter on stability of acoustic system

influence rule of geometric parameters of the disc cutter on resonance frequency and amplitude of acoustic system is studied. Vibration mode of ultrasonic cutting acoustic system of disk cutter is determined by vibration test of graphite powder. Influence of thickness

wedge angle and diameter of the disk cutter on the resonant frequency and amplitude of the acoustic system is studied by simulation and experiment. The primary and secondary relations of influence geometric parameters of the disc cutter on resonant frequency and amplitude are analyzed by Taguchi method. Through regression analysis method

study on linear relationship between disc cutter geometry parameters and resonant frequency

which provides theoretical guidance for the design of the disc cutter. The results show that with the increase of the thickness of the disc cutter

the resonant frequency of the ultrasonic cutting system increases and the amplitude also shows a trend of increase. While wedge angle of the disc increases

resonant frequency decreases and the amplitude also shows a trend of decreases. While diameter of cutter increases

the resonant frequency decreases

but the amplitude has no certain change law. The diameter of the disk cutter has the most significant effect on resonant frequency and amplitude.
