Nowadays industries are looking forward for a sustainable manufacturing. Nanofluid with minimum quantity lubrication is one technology in the areas of green manufacturing, which minimizes the pollution caused to the environments. The aim of this work was to examine the influence of silver nanoparticles-based cutting fluid with minimum quantity lubrication in turning on titanium (grade 2) by changing the environmental conditions. Taguchi's L 27 orthogonal array has been selected to execute the experimental trials. The responses considered are surface roughness, temperature and tool wear. The process parameters selected for this analysis were environment, cutting speed, feed and depth of cut. The principal component analysis was used to determine the optimal conditions in turning parameters. It was noticed that environment is the key parameter in defining the responses. Under optimal conditions, the surface roughness has been decreased by 89%, temperature has been reduced by 44% and wear on the tool has also been reduced. The tool wear and chip morphology were reviewed through scanning electron microscope for a complete study.

“…The graphene nanoparticles has two-dimensional structure which the particles were ease to slide slide between the two mating surfaces, thus improved in term of friction. Nevertheless, the inclusion at higher concentration of graphene in MJOg3 causes some coagulation that promoting the poor frictional properties due to the unstable friction as well as exhibited vibration in the friction zone [19]. Furthermore, the trend of COF for MJO blended with hBN was a bit differ from graphene nanofluids as the lowest concentration (0.01 wt.%) at MJOh1 has recorded the lowest COF of 0.0509 compared with MJOh2 and MJOh3.…”

Recently, manufacturing industries have concerned about the utilization of mineral-based metalworking fluids because of the numerous deleterious impacts on the health of workers and the environment as well as the shortage of mineral resources. Due to this scenario, the vegetable-based oils have emerged the researchers’ attention as a suitable replacement for the mineral based metalworking fluids since it is highly biodegradable, low toxicity and renewable resources. Nevertheless, the main problem of the utilization of the vegetable-based oils is that it shows poorer thermal and oxidative stability. The great development technologies had influenced the application of the nanofluids by adding the nanoparticles additives to the base oil as it gives better physical and properties, thus improved the tribological behavior. This study focuses on developing a new green synthesis and formulation of nanofluids from chemically modified jatropha oil by blending with nanoparticles additives such as hexagonal boron nitride (hBN) and graphene at the minimum concentrations (0.01, 0.025 and 0.05 wt.%). The physical testing such as kinematic viscosity, viscosity index and flash point were conducted and compared with commercial synthetic ester (SE). Then, tribological testing was performed by using four ball tribo test and analyses in terms of coefficient of friction, worn surface analysis and surface roughness. From the results, the sample of MJOs had showed an enhancement by providing higher viscosity index. The results demonstrate that MJOg2 provided the lowest coefficient of friction while MJOh3 and MJOg3 had smoother worn surface as it has lowest value of surface roughness in comparison with others sample. It can be concluded that the MJO samples have high potential substitution to mineral-based oil as a sustainable metalworking fluid in machining processes.

“…With optimal trials under graphene as nano fluids (A3Vc3f1d3), less surface tension and less contact angle make them to participate effectively at the machining zone [17]. Also, graphene nano particles has a two-dimensional sheet arrangement which make them to act as ball bearings and better piercing ability make them to minimize the friction and provide excellent cooling action at the machining zone [17]. Therefore, the consequences are less saw tooth caused (Fig.…”

“…The authors pointed out that a reduction in friction was observed as nano fluids deliver admirable lubrication at the machining zone. Lv et al [17] stated that a reduction in coefficient of friction is found due to efficient penetration of graphene nanoplatelets in milling on AISI 304.

Minimum quantity lubrication is an extensively accepted lubrication system owing to its improved heat removal in the machining areas. The purpose of the current study is to examine the effectiveness of graphene based nanofluids in turning on D3 tool steel with minimum quantity lubrication. Experiments were executed with Taguchi's L27 orthogonal matrix array. The effectiveness were examined with the machining parameters under environment (dry condition, flood lubrication and minimum quantity lubrication), cutting speed, feed rate and depth of cut in terms of surface roughness, cutting temperature, tool wear and chip morphology. A technique known as Preference Ranking Organization Method for Enrichment Evaluations were used to determine the imperative parameters governing the responses. The results reveal that graphene nanofluids with minimum quantity lubrication found to be a right substitute in reducing the surface roughness, tool wear and cutting temperature.
