Cavitation-induced erosion plays an important role in the material removal process of ultrasonic-assisted fluid jet machining. The influence of the ultrasonic and hydrodynamic parameters on the cavitation features was investigated in the present study. A numerical method was used to model the cavitation involved in the fluid jet flow field under the ultrasonic vibration condition. Experiments were also carried out to evaluate the cavitation erosion in ultrasonic-assisted fluid jet machining. The results indicated that the cavitation intensity has strong relations with the ultrasonic power output and frequency.
