The influence of feed rate parameter of milling on natural fiber surface is investigated with constant 1700 rpm spindle speed. In this study, a surface texture-measuring instrument and optical microscope are used as measurement equipments. Ramie fiber composite samples are machined at 2, 4 and 6 mm/min feed rates each. The results shows that the sample machined at 4 mm/min feed rate has the lowest surface roughness value and its surface has a harmonious structure. In addition, many cracks and fractures appeared on the sample surface which machined at 6 mm/min feed rate due to the impact of the cutting edges.
