Burrs have been defined as undesirable projections of material beyond the edge of a workpiece during machining. Burrs are created around the edge of the workpiece due to plasticity during the mechanical manufacturing process. Finally, the quality of the finished parts plays a very important role in the performance of the product. Generally, burrs have been removed by methods of physics and chemistry. However, there are a few publications in the area of applying ultrasonics to deburring. When ultrasonic vibration propagates in a liquid medium, a large number of bubbles are formed. These bubbles generate an extremely strong force, which removes burrs. The object of this study is to analyze the effects of ultrasonic cavitation and the difference between ductile and brittleness material in the deburring process. The experimental parameters to verify the deburring effects of ultrasonic cavitations are distance of the transducer from the workpiece and ultrasonic power. It was found from the results that deburring with ultrasonic cavitation in a liquid medium is effective to micro burr.
