The aerospace and automotive industries make extensive use of aluminium and its alloys. Contrarily, machining of aluminium (Al) alloys presents a number of difficulties, including, but not limited to, poor surface finishing, excessive tool wear, decreased productivity etc. Therefore, it’s very important to measure the machining characteristics during machining of aluminium alloy with sustainable cooling strategies. In this work, a new approach of measurement was adopted to measure the critical geometrical aspects of tool wear, surface roughness, power consumption and microhardness while machining AA2024-T351 alloy under dry, minimum quantity lubrication (MQL), liquid nitrogen (LN2) and carbon dioxide (CO2) cooling conditions. Initially, the various aspects of tool wear were studied with the help of Sensofar Confocal Microscope integrated with Mountains map software and then, the other results such as surface roughness, power consumption and microhardness were measured as per the ISO standards. The outcome of these measurement studies confirms that LN2 and CO2 cooling is helpful in improving the machining characteristics of AA2024-T351 alloy. When compared to dry conditions, the surface roughness values of MQL, LN2, and CO2 all have values that are lowered by 11.90%, 30.95%, and 39.28% respectively, and also power consumption values were lowered by 3.11%, 6.46% and 11.5% for MQL, CO2 and LN2 conditions, respectively.

This research investigates the performance of high-speed CNC milling operations on Ti6Al4V alloy by employing a novel ZnO-Ag hybrid nanofluid. The study involves the preparation and characterization of nanofluids with varying concentrations of nanoparticles, focusing on thermal conductivity and stability. The machining experiments encompass four critical input parameters: Minimum Quantity Lubrication (MQL) flow rate, cutting speed, nanofluid concentration, and feed rate. Performance evaluation is based on average surface roughness (Ra) and cutting temperature. Key findings include a remarkable 21.05% improvement in thermal conductivity for the ZnO-Ag-based sunflower oil at 0.2% volume concentration compared to 0.05% concentration. The prepared nanofluids exhibit good stability. Moreover, cutting speed and MQL flow rate emerge as significant contributors to Ra, accounting for 35.62% and 34.82%, respectively. Interestingly, MQL flow rate is identified as the most influential factor, surpassing even cutting speed. SEM images for tool wear reveals that the ZnO-Ag based sunflower oil reduced tool wear significantly. In conclusion, the proposed ZnO-Ag-based sunflower oil at 0.2% concentration emerges as the good option for sustainable high-speed machining of Ti6Al4V alloy, showcasing

Super-duplex stainless steel (SDSS) 2507 is a type of material known for its outstanding mechanical properties and superior corrosion resistance due to its complex microstructure and the presence of various alloying elements. However, due to these characteristics, machining this material can be challenging. To address this issue, manufacturing industries have been exploring innovative ways to use lubricants during machining while considering their environmental impact. Manufacturing industries have been making efforts to move away from using large amounts of lubricants and instead adopt minimum quantity lubrication techniques. Meanwhile, the advantages of using textured surfaces in improving tribological properties have also been recognized. A lot of research has been done to enhance the performance and durability of components by modifying their surface topography. Recently, textured surfaces have also been applied in cutting tools. The use of micro dimples or linear grooves on the rake or flank face of the tool has been shown to reduce cutting forces, friction coefficients, and cutting temperatures. Consequently, this has led to improvements in machining output parameters and increased tool longevity. This study proposes a new sustainable machining approach by combining two techniques: the use of surface textured tools and minimum quantity lubrication (MQL). Two types of cutting tools were used in the experiment: a surface textured tool with circular pit holes, and a hybrid texture tool with a combination of circular pit holes and linear grooves, both under MQL. The experiments are planned based on fractional factorial design and measured cutting forces and tool flank wear were compared with the predicted forces in order to validate the feasibility of the proposed design. The contribution of each process parameter was determined through the analysis of variance (ANOVA) to assess the percentage impact of each parameter. The cumulative effect of both circular and perpendicular textures provides the hybrid texture with superior debris entrapment capability while acting as a chip breaker which reduces the adhesion between the chip and the insert, resulting in better surface finish and wear resistance and hybrid texture tool significantly reduced the tool flank wear and cutting force.
