Outline of Final Research Achievements

The developed process is a method for actively and efficiently implementing surface modifications (functionalization) to workpieces during precision fabrication (grinding/cutting). Using this method, it is possible to control a mechanical–chemical reaction phenomenon between the tool material and the workpiece material. Using this method, a micro-tool with a diameter less than 1 µm has been successfully developed. Furthermore, this method has been attracting considerable attention in the field of production technology such as in ultra-precision molds and bio-implant components. A cytocompatibility of surface modified metallic bio-material was evaluated by the developed cell culture/friction abrasion testing integrated system. The obtained results make expanding some novel research topics such as diamond milling of bio-medical micro devices and a specific laser induced local surface treatment technique.
