Functional surfaces have been widely used for control of physical and/or chemical properties of substances on the surface. The surface functions have been controlled by coating or the other processes in terms of material treatment so far. Recently, the advanced micro fabrications have also been applied to manufacturing of the functional surfaces. This study presents a fabrication of the micro scale structures on surfaces in millings with end mills having textured edges. In the fabriacation, the end mill is fed back and forth with controlling the spindle axis inclination alternately. The textured edge was finished on a PCD end mill in laser processing with reducing the irradiation diameter on a developed machine. The cutting tests were conducted to verify the presenting fabrication with the end mill, on which the texture shape is formed with a pitch of 10 μm at an apex angle of 90 degrees. The micro asperities were fabricated on surfaces with nealy the same size as the texture one of the edge.
