Depth and Horizontal Distance of Surface Roughness Improvement on Vertical Surface of 3D-Printed Material Using Ultrasonic Cavitation Machining Process with Abrasive Particles

摘要

An investigation has been carried out on the effects of abrasive-aided ultrasonic cavitation machining process on improving the surface roughness of 3D-printed material. The test surface will be placed in a vertical orientation aligned with the central axis of the ultrasonic horn rather than horizontally as commonly practiced. Experimental parameters of abrasive concentration and size is used and the effect on surface roughness at both vertical and horizontal distances away from the horn is examined. It is found that larger abrasive concentration has a positive effect on the depth of surface roughness improvement while a limitation is observed for larger abrasive sizes. No trend in surface roughness improvement is found with respect to the horizontal distance from the horn's central axis.
