Evaluation of performance of nanofluid using multiwalled carbon nanotubes for machining of Ti–6AL–4V

Machining Performance Investigation of AISI 304 Austenitic Stainless Steel under Different Turning Environments

“…Minh et al [32] investigated nearly 35% reduction in value of surface roughness under Al2O3 nanofluid MQL machining of 60Si2Mn steel because of superior tribological and cooling action of nanoparticles in the cutting zone. Sahu et al [33] examined the performance of MWCNT nanofluid during turning of Ti-6Al-4V grade 5 titanium alloy. It was concluded that nanofluid results in 13% lesser tool wear and about 6.1% lower surface roughness compared to conventional coolant at cutting velocity of 90 m/min.…”

Nanofluid as an Alternative Coolant in Machining: A Review

“…Reddy and Rao mentioned that the specific energy of the nanoparticles is effective in reducing the frictional forces between the tool and workpiece which leads to reduction in cutting force [22]. Raju et al, and Sahu et al, reported that the nanofluid improved lubricant properties leads to a high wettability and enables to lubricate the cutting zone much better while resulting in lesser frictional force [23,24]. According to Lee et al, and Zhou et al, nanofluids tends to reduce the cutting force due to its friction coefficient which evaluate the characteristics of a lubricant [25,26].…”

“…Reduction in Cutting Force [19] Coconut oil (CC) + nano molybdenum disulphide (nMoS2) 37 percentage of reduction [20] Alumina based fluid with graphene nano plates 9.94% reduction in cutting force [22] Graphite, Molybdenum disulphide (MoS2) 20% of reduction for graphite powder and 28% reduction for MoS2 powder. [23] Multi wall carbon nanotubes and distilled water with sodium dodecyl sulphate as surfactant 5 to 8 percentage reduction [25] Mineral oil with graphite nanoparticle 24% of reduction [27] Aluminum Oxide added to the conventional cutting fluid 50% of reduction [26] Fe3O4 with conventional coolant 38.4% reduction [28] Nano boric Acid with coconut oil 14.5% reduction than dry machining [30] Al2O3 with carbon nanotube (CNT) in vegetable oil 11.8% reduction [24] MWCNT nanofluid with distilled water 28% drop of cutting force [29] Natural777 oil based diamond nanoparticle 10.71%…”

“…Sahu et al, mentioned that high surface area of the MWCNT; results in high heat transfer rate that helps to tool wear reduction [24]. The author also stated that even at low particle concentration the nanofluids are better as heat transfer fluid.…”

“…Flank wear occurs after 292 seconds of machining [24] MWCNT nanofluid with distilled water Average flank wear occurs at cutting length of 960 mm [48] Al2O3 with vegetable oil Up to 26.5% of flank wear reduced [57] ZnO, CuO, Fe2O3 and Al2O3, with distilled water Crater wear and flank wear reduced [50] Ethylene glycol based TiO2 Flank wear occurs after 940 mm cut length Figure 1 shows the nanofluid forming a thermal barrier between chip and cutting tool. According to Kadirgama et al, the small chip shows the presence of less aluminum percentage proves that the nanofluid is capable to carry away the heat generated due to the superior thermal conductivity properties [36].…”
