Analysis of cavitation orthogonal experiments in power ultrasonic honing

Abstract

Cavitation will occur in the process of power ultrasonic honing. To explore the influence of cavitation on the material surface processed, an ultrasonic honing cavitation orthogonal experiment is conducted and three indicators are analyzed, which are pits’ maximum diameter, surface erosion rate, and surface roughness and can represent the single bubble collapse strength, the whole cavitation strength, and the impact of cavitation on material surface quality, respectively. The results show that cavitation leads to micro-pits on material surface. The main factors influencing the pits’ maximum diameter are distance and amplitude in turn; meanwhile, the shorter distance and the greater amplitude result in the larger pits’ maximum diameter. The surface erosion rate is mainly affected by experiment time and distance in order. Amplitude has the greatest influence on the surface roughness. The sample surface roughness reduces and surface quality improves in the condition of distance of 5 mm, amplitude of 65%, and experiment time of 1/3 min. Therefore, cavitation effect can help to enhance the workpiece surface quality in power ultrasonic honing under certain conditions, and the experimental analysis results have reference significance to the actual processing of ultrasonic honing.
