FABRICATION OF MICROFLUIDIC CHANNEL USING

2011-7-18  Among the M4 techniques, micro end milling has shown great potentials in the fabrication of microfeatures. The motivation comes from the translation of the knowledge obtained from the conventional process to the micro level. Its specialty includes the ability of fabricating microfeatures from wide varieties of materials with complex three dimensional geometries. The master micromold produced by micro end milling can be used economically in microreplication. However, several macro rules are not directly applicable when machining in the micro/meso scale due to the size effect (Ahn et al., 2005; Ahn and Ronney, 2005). In this research, two-flute tungsten-carbide end milling tools were used for machining microchannels
