Ultrasonic machining is fast becoming popular today. The purpose of this study is to explore how various ultrasonic horn shapes can affect non-contact ultrasonic abrasive machining. Due to the wide nature of ultrasonic horns, a multitude of possibilities lie ahead. By varying certain geometrical parameters of the horn design, it is possible to accomplish a very different finishing. Non-contact ultrasonic abrasive machining, not limiting to, primarily relies on acoustic cavitation for material removal. As such, this study aims to determine how varying the horn design can affect the acoustic cavitation phenomenon and in turn, improve on the quality of the finishing when utilising non-contact ultrasonic abrasive machining. Through this study, results concur with past literature on how the resonant frequency and intensity can vary with different horn designs. As this is a rather broad topic, this report serves as a preliminary guide on the question at hand. Many other factors such as horn and material combinations can and should be considered in the future.
