Novel cutting tools that had either microscale or nanoscale textures on their surfaces were developed in this study. Texturing microscale or nanoscale features on a solid surface allowed us to control the tribological characteristics of the tool. In this report, diamond like carbon (DLC) coated tools with the texture were developed using a femtosecond laser and subsequent DLC coating methods. By applying DLC coating, the effects of the texture were evaluated without adhesion of a work material due to its low adhesion rate and application of the texture to coated tools can also be investigated. Turning experiments of aluminum alloy were performed under the various cutting conditions. It was found that the wet condition was suitable for the developed tool and the further decrease in cutting forces were observed when the texture was applied to the DLC coated tools. The tendency of the direction of the texture was similar to that of the noncoated textured tools, which indicates that the difference in the effect of the texture was decided not only by the adhesion characteristics of the work material but also by other factors. The effects of the texture were observed even at the low cutting speed. These results indicate that the textured tool is applicable for the DLC coated tool.
