Abstract

ABSTRACT 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 740–273 nm were produced utilizing different wavelengths. Additionally, beamshaping technology increased productivity by 4008% up to 105 cm2 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.

通过波束整形技术提高AlTiN的摩擦学性能和纳米结构速度

摘要动态波束成形技术首次被用于在AlTiN涂层上高效生产周期性纳米结构，从而实现干式加工，而无需昂贵且对环境有害的切削液。首先，周期在740–273之间的各种周期性纳米结构利用不同的波长产生nm。此外，光束整形技术通过将高斯光束整形为500的矩形光束，将生产率提高了4008%，最高可达105 cm2 min−1 × 30 µm。为了模拟制造过程中的应用负载和由此产生的热量，在室温和500°C的高温下进行摩擦分析。分析显示，摩擦系数显著降低——在室温和500°C下分别高达27%和19%。这些结果的结合表明，所提出的方法可以大规模生产用于干式加工的功能化加工工具。
