“…Cutting with MQL + Al 2 O 3 decreased the power consumption even more than the case of using MQL; see Figure 6 . Bai et al [ 30 ] reported that the addition of nanoparticles to MQL oil increases the viscosity of the fluid which formed a thin layer of oil film on the friction surface of the workpiece. This can improve the oil adsorption effect, thus improving the lubrication performance and helping in reducing friction and wear compared to the case of using pure oil.…”

“…The decrease in power consumption in MQL and MQL + Al2O3 compared to dry case was 4.7% and 8.6%, respectively. This is due to the effectiveness of lubrication by MQL in reducing the friction of chip-tool interface which results in reduction on cutting force [30], thus less power was consumed compared with the case of dry machining. Besides, using MQL in cutting prevents built-up edge formation and rapid tool wear which lead to a reduction in cutting force and power consumption [31].…”

In this paper, an experimental investigation into the machinability of AISI 316 alloy during finishing end milling operation under different cooling conditions and with varying process parameters is presented. Three environmental-friendly cooling strategies were utilized, namely, dry, minimal quantity lubrication (MQL) and MQL with nanoparticles (Al2O3), and the variable process parameters were cutting speed and feed rate. Power consumption and surface quality were utilized as the machining responses to characterize the process performance. Surface quality was examined by evaluating the final surface roughness and surface integrity of the machined surface. The results revealed a reduction in power consumption when MQL and MQL + Al2O3 strategies were applied compared to the dry case by averages of 4.7% and 8.6%, respectively. Besides, a considerable reduction in the surface roughness was noticed with average values of 40% and 44% for MQL and MQL + Al2O3 strategies, respectively, when compared to the dry condition. At the same time, the reduction in generated surface roughness obtained by using MQL + Al2O3 condition was marginal (5.9%) compared with using MQL condition. Moreover, the results showed that the improvement obtained in the surface quality when using MQL and MQL + Al2O3 coolants increased at higher cutting speed and feed rate, and thus, higher productivity can be achieved without deteriorating final surface quality, compared to dry conditions. From scanning electron microscope (SEM) analysis, debris, furrows, plastic deformation irregular friction marks, and bores were found in the surface texture when machining under dry conditions. A slight smoother surface with a nano-polishing effect was found in the case of MQL + Al2O3 compared to the MQL and dry cooling strategies. This proves the effectiveness of lubricant with nanoparticles in reducing the friction and thermal damages on the machined surface as the friction marks were still observed when machining with MQL comparable with the case of MQL + Al2O3.

“…Conversely, a high viscosity value was responsible for lowering the flowability characteristics of any lubricant. In actual, as the viscosity increased, the flowability of lubricant was reduced; consequently, the lubrication time was also enhanced [63]. However, Alves et al revealed that a high viscosity leads to strengthening the absorption film produced by nano-lubricants [64].…”

In modern days, the conception of sustainability has progressively advanced and has begun receiving global interest. Thus, sustainability is an imperative idea in modern research. Considering the recent trend, this review paper presents a summary of the previously published research articles on minimum quantity lubrication (MQL) assisted machining. The requirement to stir towards sustainability motivated the researchers to revise the effects of substitute lubrication methods on the machining. Conventional lubri-cooling agents are still extensively employed when machining of engineering alloys, but the majority of the recent papers have depicted that the utilization of vegetable oil, nanofluids, and nanoplatelets in MQL system confers superior machining performances as compared to conventional lubrication technology. In actual, the definite principle of this manuscript is to reexamine modern advancements in the MQL technique and also explore the benefits of the vegetable oil and nanofluid as a lubricant. In brief, this paper is a testimony to the advancing capabilities of eco-friendly MQL technique which is a viable alternative to the flood lubrication technology, and the outcomes of this review work can be contemplated as a movement towards sustainable machining.

“…Further than that, recently researchers have found excellent results by adding nanoparticles into MQL. Different types of nanoparticles were used by researchers including SiO 2 , Al 2 O 3 , MoS 2 , ZrO 2 , CNT, SiC, PCD, and graphite [9,10] while others are under investigation. The effectiveness of nanoparticles has been reported in turning [11][12][13], milling [14,15], drilling [16] for better surface quality, prolonged tool life, reducing cutting force, reducing tool wear, and reducing power & energy consumption.…”

Surface roughness is an important assessment of metal cutting. This paper presents an empirical investigation of cutting conditions on the surface roughness in hard milling SKD61 steel. The cutting speed, feed rate, depth of cut, and nanoparticle concentration were taken as the parameters in the experimental setup. The mixer of SiO 2 particles with a size of 100nm based on cutting oil CT232 was used with 3 levels of concentration: 0, 2, and 4wt%. Twenty-seven experiments were carried out based on the DOE method developed by G. Taguchi. The best model from response surface methodology (RSM) was developed regarding the surface roughness. Further analysis with ANOVA method was performed to confi rm the signifi cant of the achieved model as well as machining parameters. According to experiment results, the weight percent of nanoparticles concentration had a great impact on the surface roughness, only after the feed rate. Additionally, the excellent effectiveness in reducing the roughness of MQL nanofl uid has been demonstrated when compared with conventional MQL.
