Three-dimensional micro-texturing technology using micro form rolling

There is increasing demand to reduce friction in engine and transmission parts. Friction between sliding surfaces can be reduced by processing micrometer-scale surface textures with controlled cross-sectional geometry. We have developed 3-dimensional micro-forming technology, to fabricate such controlled surface textures at high efficiency. Here, we present the high-efficiency micro-texturing method Micro-Form Rolling (MFR), and discuss the machining properties of MFR. MFR could be used to machine 3-dimensional micro-textures with high efficiency. Furthermore, tool life of MFR could be improved by controlled the tool shape.
