“…The similarity between the surface roughness of the grinded samples with some of biodegradable formulations and the surface roughness of the samples grinded with mineral oil reveals the potential of vegetal-based cutting fluids as substitutes for mineral-based oils. These observations are in line with the results obtained by Wang et al 17 , where it was found that grinding operations with vegetable oils promote good surface quality, which is directly related to the roughness of the component 17 . Figures 3-6 shows the microstructures of the samples analyzed by SEM in order to investigate possible microstructural changes resulting from damage to the material sub-surface due to thermal and mechanical stresses inherent to grinding process.…”

“…Many works reports a relation between the surface integrity of machined components and their functional performance, regarding tribological properties, fatigue strength and stress corrosion cracking resistance 4,15,16 , justifying the importance of improving the different cooling technologies applied in grinding process to reduce thermal damage and the problems that affect the surface quality of components. The gathered heat leads to high temperature, and without the lubrication and cooling effect of the grinding fluid, the grinding wheel wears seriously, and the workpiece precision and surface integrity deteriorate 17 . Mineral oil based cutting fluids is the most common type of lubricant used in metalworking industry.…”

Surface integrity has significant effect on service performance of a component. The surface integrity of workpieces submitted to grinding process depends on the conditions of cooling produced by cutting fluids, which are used to avoid microstructural damage in the process. However, cutting fluids are harmful to the environment and human health, and appear as a crucial element to the optimization of the manufacturing process. In this scenario, biodegradable cutting fluids, such as formulations based on vegetable oils, appear as promising possibility to a cleaner production in grinding process. This study analyzed the surface integrity of AISI 4340 steel, quenched and tempered, in the external cylindrical plunge grinding process with the use of six different formulations of biodegradable cutting fluids (with oils of soybeans, corn, and mineral oil, pure and with additives). The performance of the application of cutting fluids was evaluated by characterizing the microstructure by Scanning Electron Microscopy -SEM and microhardness and roughness measurements. The results showed that the surface integrity of the components was not significantly damaged, which proves the efficiency of biodegradable cutting fluids and feasibility of its use in grinding process.

“…After comparing olive oil used MQL with other coolant application models, they concluded that MQL was the best mode for sustainable machining system. A few years ago, Wang et al [53] calculated the lubricating properties of various vegetable oils in grinding of GH4169. Depending upon the experimental outcomes, the rank has been established as follows: maize oil < rapeseed oil < soybean oil < sunflower oil < peanut oil < palm oil < castor oil.…”

“…The lubrication property of these vegetable oils was mainly evaluated in terms of grinding force, specific grinding energy, friction coefficient, grinding ratio, and surface morphology. Figure 9 [53] shows the morphology of grinded surfaces under flood, paraffin oil, and different vegetable oil based lubri-cooling conditions and the summary of the above-reviewed literature on VMQL is shown in Table 1.…”

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.

“…VOs have high adsorption film formation capability on metallic surfaces and unsaturated long-chain fatty acids in VOs can react with metal surfaces forming a film like metallic soap. Both can improve antiwear and antifriction properties [8]. Ozcelik et al [9] examined the performance of the various VOs with (8% and 12%) extreme pressure additives (EP) on Fz, Ra and Vb in turning of AISI304L.…”

Present work is motivated by the high thermal conductivity of MWCNT and low coefficient of friction due to MoS2 nanoparticles which can significantly improve the heat transfer and lubrication performance of hybrid nanofluids than nanofluids. Hybrid nanofluids are prepared with CNT/MoS2 nanoparticles of 1wt% in sesame oil, neem oil and mahua oil by varying hybrid ratio (i.e. 1: 1; 1:2 and 2:1) and surfactant. The hybrid nanofluid composition is evaluated based on stability analysis from sedimentation and zeta potential studies. The concentration of nanoparticles is varied by preparing CNT/MoS2 hybrid nanofluid using obtained composition for stability and selected the optimal concentration for the lowest coefficient of friction obtained in friction test. The property of thermal conductivity is also evaluated for varying concentration of hybrid nanofluid at room temperature. The contact angle for CNT/MoS2 hybrid nanofluids is evaluated with a contact angle meter to understand the lubrication effect. Experimental findings for stable hybrid nanofluid are found to be sesame oil, SDS with 15% content of nanoparticle weight and 1:2 hybrid ratio. From friction test, it is observed that 2 wt%concentration is optimal for least coefficient of friction (0.038). Minimum surface roughness (Ra) is observed with 2 wt% of hybrid nanofluid compared to dry machining and conventional cutting fluid. Optimum conditions for minimum surface roughness are evaluated in turning of AISI1040 steel with the use of 2wt% of CNT/MoS2 hybrid nanofluid in RSM. Ra value is observed to decrease with an increase in cutting speed and increased with an increase in feed and depth of cut.
