Surface Roughness Characterization of Medical Implant Material SS316L Stainless Steel after Cut with Water Jet Cutting Process

In this paper, the effect of abrasive water jet cutting process on the surface character of medical implant SS316L was investigated. This research focuses on the effect of traverse speed during abrasive water jet cutting on the surface roughness and topography of medical implant material SS316L. In some study, it has been noted that the roughness of implant material correlates with the healing process of a sufferer in medical application. Furthermore, transverse speed has an important role in the manufacturing process that correlates directly with the ability of technic to produce a product at a definite time. Garnet was used as an abrasive material in this water jet cutting process. The process was taking place in room temperature with 3000Psi of water pressure. In this study, the surface roughness was examined at all point of depth of the cut surface in all of the transverse speed using Mitutoyo SJ 210, while the surface topography observed by Olympus BX53M optical microscope. The study results reveal that traverse speed has a significant effect on the surface roughness at the surface, middle, and bottom of the cut point. The Surface roughness increase as transverse speed.
