<p>Currently, the use of cutting fluid not only pollutes the environment, but also increases production costs. Therefore, dry cutting is becoming increasingly popular in metal machining. In this research, the effects of DLC self-lubricating coating and femtosecond laser texture on enhancing the dry cutting ability of an AlCrN-coated cemented carbide tool are investigated. These effects are very important for dry cutting applications and environmental protection. For this purpose, DLC/AlCrN coated tools with micro-texture were prepared by arc ion plating, laser technology and pulsed DC magnetron sputtering. The laser texture and the microstructure of the coating are evaluated using analytical tools. Through dry cutting experiments on quenched AISI5140 steel, the machining performances of different coated tools were compared. As a result, the dry cutting performance of the DLC/AlCrN coated tool is significantly improved, and the cutting force, cutting temperature, friction coefficient, and tool wear are significantly reduced compared with those of traditional AlCrN coated tools. A more important finding is that the dry cutting performance of the cutting tools is further improved due to the synergistic effect of the micron texture and the DLC coating. At high speed cutting (150&#xa0;m/min), the cutting temperature is reduced by 19.1%, the main cutting force is reduced by 13.6%, and the surface roughness of the workpiece is reduced by 40.6%, among other improvements. Considered from an other standpoint, the improvement of tool life, the reduction in cutting fluid use and the reduction in energy consumption during machining are not only critical for improving tool performance under dry cutting conditions, but also for environmental benefits. The mechanisms of DLC lubrication coating and the femtosecond laser texture effect are discussed.</p>
