Outline of Final Research Achievements |
A micro dimple machining was studied to control the surface functions with the micro-scale structures on the stainless steel, one of the implant materials. The micro dimples are machined in milling with the inclined ball end mill at high feed rates. A mechanistic model was presented to control the shape and the size of the dimples to be machined. The micro dimples were machined on a plate of fine-grained stainless steel to reduce burr formation. The depth of the affected layer was also reduced in subsurface of the machining area by the fine crystal grains. Then, wettability on the dimpled surface changes by the pinning effect at the edges of the dimples.
