In this study, in order to improve the characteristics of the vegetable-based cutting fluids used in the MQL technique and increase the machining performance of MQL and its barbie jogadora de v?lei positive effects on sustainable manufacturing, the effects of the MQL method with nano-Al2O3 additives on surface roughness (Ra) and cutting temperature (Ctt) were examined through turning experiments carried out by adding nano-Al2O3 to the vegetable-based cutting fluid.For this purpose, machining tests were carried out on hot work tool steel alloyed with Cr-Ni-Mo that has a delivery hardness of 45 HRC.In hard machining experiments, three techniques for cooling and lubricating (dry cutting, MQL, and nano-MQL), three cutting speeds (V) (100, 130, 160 m/min), three feed rates (f) (0.10, 0.125, and 0.
15 mm/rev), and two different ceramic cutting tools (uncoated and TiN-coated with PVD methods) were used as control factors.For Ra, the nano-MQL method provided an average of 21.49% improvement compared to other cooling methods.For Ctt, this rate increased to 26.7%.
In crater wear areas, the nano-MQL method again exhibited the lowest wear values, decreasing performance by approximately 50%.The results of this research showed that the tests conducted using the kit ethos boro across vape x dovpo cooling of nano-MQL approach produced the best results for all output metrics (Ra, Ctt, and crater wear).
