“…Sunflower and Canola oil based cutting fluids [26] generate better surface finish and produce lower cutting and feed forces while turning AISI 304 L. A novel cutting fluid was developed from nonedible Neem [27] performed better with respect to temperature rise at tip, cutting forces, tool wear, and surface roughness. The modified Jatropha oil [11] showed the lowest values of cutting force, cutting temperature, and surface roughness, with a prolonged tool life and less tool wear. Coconut oil with 0.5% nanoparticle inclusions resulted in improved machining performance compared to Sesame oil and Canola oil [28].…”

“…Vegetable oil-based cutting fluids are highly biodegradable, eco-friendly, renewable, less toxic, high flash point, low volatility, high viscosity index, wide production possibilities, and economical in the waste management [9][10][11][12]. Vegetable oils primarily consist of triglycerides; [13][14][15] the triglycerol structure of vegetable oil makes it a strong competitor as a base stock for lubricants and functional fluids [16].…”

Owing to the desirable properties of vegetable oils as cutting fluids, an attempt is made to explore the potentiality of plentifully available vegetable oils as a cutting fluid for turning AA 6061. Two nonedible vegetable oils, Jatropha and Pongamia, in their chemically modified (epoxidized) versions are used as straight cutting fluids. Cutting fluids are introduced to the machining zone with the aid of Minimal Quantity Lubrication (MQL) method. Taguchi's technique of orthogonal arrays is used to develop an effective design of experiments. The results obtained under epoxidized versions of Jatropha and Pongamia oils are compared with the results of mineral oil in terms of cutting forces and surface roughness. Experimental observations and statistical analysis show that, compared to mineral oil, the modified versions of vegetable oil-based cutting fluids are more effective in reducing the cutting forces and increasing surface finish. It is also observed that the modified Pongamia oil showed lesser flank wear compared to the other two tested oils.

“…As an excellent additive for lubricating oils, h‐BN can significantly improve the fiction‐reducing and antiwear properties. Until now, many studies on the lubrication performances of h‐BN have been reported . Çelik et al prepared h‐BN particles using a special process and investigated the tribological behaviors of the h‐BN particles as additive in the engine oil.…”

Hexagonal boron nitride nanosheets (h‐BNNSs) are obtained by a chemical exfoliation method from bulk h‐BN powders. The surface of h‐BNNSs is functionalized with 3‐aminopropyltriethoxysilane (APTS). Further, the amino functional groups on the surface of APTS‐modified h‐BNNSs (APTS‐BNNSs) are reacted with 4‐carboxyphenylboronic acid (CPBA) to obtain the covalently linked CPBA‐BNNSs. The morphology and structure of h‐BNNSs, APTS‐BNNSs, and CPBA‐BNNSs are comprehensively discussed. Of all the above four additives, the CPBA‐BNNSs can most outstandingly improve friction‐reducing and antiwear capacities of 150N base oil. The CPBA‐BNNSs possess excellent dispersion stability in base oil due to the phenylboronic acid groups on the surface of h‐BNNSs. Only 0.075 wt% CPBA‐BNNSs is added into the base oil, the coefficient of friction is decreased by 32.3%, and the wear scar diameter and mean wear volume of the rubbing surface are reduced by 42.9% and 88.4%. The analysis of the worn scar surface demonstrates that CPBA‐BNNSs can form a protective tribofilm containing boron and nitrogen elements on the rubbing surfaces, thereby decreasing the friction and protecting the surfaces from wear. Thus, the CPBA‐BNNSs may be recommended as a potential lubricant additive in practical applications.

“…Metalworking fluids (MWFs) are used as a lubricant in machining processes to increase tool life, enhance machining efficiency and provide excellent surface quality and accuracy by means of both cooling and lubricating at the tool-workpiece in-Modern Mechanical Engineering terfaces [1]. More than 50% of all lubricants used globally are petroleum based and have adverse effects on environment due to improper disposal, toxicity and non-biodegradability.…”

Lubricants are playing an important role in world industrial and economic development, mainly by reducing friction and wear in mechanical contacts. The outlook for eco-friendly MWFs for the next decade is 15% of global volume share. Due to ever increasing demand for environmentally acceptable products suitable for use as MWFs, vegetable oil-based MWFs are drawing the attention of researchers across the globe. Owing to the desirable properties of vegetable oils as cutting fluids, vegetable oil-based cutting fluids play an important role in conserving the environment by means of sustainability. This paper focuses on various vegetable oil being developed to promote biodegradable MWFs across the world. The performance of vegetable oils with respect to cutting and thrust force, tool wear, temperature, surface roughness in turning, drilling, milling and grinding a wide variety of materials are studied and reported. The review also throws light on the tribological behavior of vegetable oils that influence the lubricity in Metal working process. The review reveals that vegetable oils offer an alternative, eco-friendly and sustainable MFWs for the future of manufacturing.
