Annotation	For the first time,a dynamic beamshaping technology has been utilized for the efficient production of periodic nanostructures on top of AlTiN coating to enable dry machining without costly and environmentally hazardous cutting fluids.First,a variety of periodic nanostructures with periods in a range of 740–273nm were produced utilizing different wavelengths. Additionally, beamshaping technology increased productivity by 4008% up to 105cm2 min−1 by shaping the Gaussian beam into a rectangular beam of 500 × 30 µm.To simulate the application load and resulting heat production during manufacturing,friction analysis was performed at room and elevated temperature to 500°C.The analysis revealed a significant reduction in the friction coefficient – up to 27% and 19% at room temperature and 500°C, respectively.The combination of these results demonstrates that the proposed method can be scaled up for the mass production of functionalized machining tools for dry machining.
