This paper primarily determined the suitable technique for the preparation of WS₂/C coating by the analytical hierarchy process (AHP) with a keen focus on the criteria of coating property, deposition process, resource and equipment. Further, some cutting performances of six cutting tools with different treatments, including cutting forces, cutting temperatures, wear mechanisms, tool life, etc. were investigated in dry cutting AISI1045 steel. The optimal lubricating condition for dry cutting process was obtained when using the cutting tools configured with the combination of WS₂/C coating and shark-skin-inspired structures. Finally, the sustainability assessment was carried out by the calculation of the product sustainability index (PSI). The highest PSI of 78.6% was obtained in case of the dry cutting experiment using WMT-2-N tools, which provided a suggested favorable alternative considering both product and manufacturing process. Thus, dry cutting AISI1045 steel using WMT-2-N tools seems to be an environmentally-friendly machining process and would be helpful to enhance sustainability.

本文主要确定了通过层次分析法（AHP）制备WS ₂ / C涂层的合适技术，并着重研究了涂层性能，沉积工艺，资源和设备的标准。此外，在干切削AISI1045钢中，研究了六种不同处理方式的切削刀具的切削性能，包括切削力，切削温度，磨损机理，刀具寿命等。当使用配置有WS ₂组合的切削工具时，可以获得干切削过程的最佳润滑条件。/ C涂层和鲨鱼皮启发的结构。最后，通过产品可持续性指数（PSI）的计算来进行可持续性评估。在使用WMT-2-N工具进行干切削实验的情况下，获得了78.6％的最高PSI，考虑到产品和制造工艺，这提供了一个建议的替代方案。因此，使用WMT-2-N工具对AISI1045钢进行干切削似乎是一种环境友好的加工工艺，将有助于提高可持续性。
