A reduction in cutting force achieved by using the textured tools was confirmed even under dry conditions. The results of orthogonal cutting tests for carbon steel with non-textured and micro textured tools indicated that both of cutting force components definitely reduces through reduction in tool-chip contact length at cutting speeds higher than 150 m/min. In addition, tests employing various textured tools suggested that effective textures possess ridged patterns perpendicular to the chip flow direction. Moreover, from results of the tests using tools with sectionally textured surfaces, it was revealed that the textures located at an area where friction state changes from adhesion friction to sliding one bring about the cutting force reduction.
