Abstract: In the presently application of removing metal burrs by combination of ultrasonic amplitude rods and abrasive particles, although theoretical research on individual ultrasonic cavitation bubbles is becoming increasingly mature, there is a lack of study on the effect of water temperature on the maximum collapse pressure of cavitation bubbles. This article uses HyperMesh and LS-DYNA Program Manager to simulate the dynamic process of a single cavitation bubble collapsing and impacting a workpiece. Based on the theory of maximum collapse pressure of a single ultrasonic cavitation bubble, ANSYS Workbench is used to analyze the collapse effect of a single cavitation bubble uniformly distributed on the surface of drilled burrs. When the liquid medium is filled within the hemispherical region of the spherical excitation focused ultrasonic cleaning machine, COMSOL Multiphysics three-dimensional acoustic field simulation and the aluminum foil corrosion method demonstrate the formation of a stable local high-pressure acoustic region at the center of the circle, and drilling burr removal experiments are conducted in this region. The experiment results indicate that the increasing in water temperature can effectively improve the efficiency of burr removal.
