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.

The raw and modified versions of two nonedible vegetable oils, Pongam (Pogammia pinnata) and Jatropha (Jatropha curcas), and a commercially available branded mineral oil are used as straight cutting fluids for turning AA 6061 to assess cutting forces. Minimum quantity lubrication is utilized for the supply of cutting fluids. Cutting and thrust forces are measured. Cutting power is determined for various cutting speeds, depths of cut, and feed rates. Also, drilling is performed on the material to understand the material removal rate (MRR) under these oils. The performances of vegetable oils are compared to mineral oil. A noticeable reduction in cutting forces is observed under the Jatropha family of oils compared to mineral oil. Further, better material removal rate is seen under both the vegetable oils and their versions compared to under petroleum oil for the range of thrust forces.

Cutting fluid is a vital part of the machining process. Cutting fluid is significantly applied tolower the friction and heat generated in the machining zone. It also helps in easy chip removal, protection against oxidation, tool life improvement, and an overall improvement in the quality of the product. The current industrial practices are majorly emphasized on mineral-based oil application under flood lubrication to achieve superior quality. However, these oils and techniques are toxic and environmentally unfriendly. Machining under dry or with minimum quantity lubrication (MQL) has been mostly preferred to eliminate the use of abundant oil. The current research work has established the promising potential for vegetable oils as a cutting fluid under MQL during turning of AISI 4130 steel. The results inferred that vegetable-based cutting fluids performed better over mineral-based cutting fluids in terms of lower values of machined surface roughness, tool wear, cutting forces, and chip-tool interface temperature. The MQL machining performance in terms of cutting forces, surface roughness and tool life has been observed better in comparison to machining under flood and dry cutting conditions.

Cutting fluids play a major role in machine operations, life of tools, workpiece quality and overall high productivity which are considered as potential input for minimal tool wear, minimal surface roughness and better machining finished product owing to the ability to prevent overheating of the workpiece and cutting tool. In this paper, the challenge of environmental biodegradability, tool wear and workpiece surface roughness prompt the need to evaluate and compare the performance of Jatropha oil based cutting fluid (JBCF) with mineral oil based cutting fluid (MBCF) during turning with AISI 304 Alloy steel which are presented. Test were conducted on the Physiochemical property, fatty acid composition (FAC), cutting fluids formulation of oil ratio to water ratio in proportion of 1:9, turning operation and response surface methodology (RSM) design of experiment were carried out and used respectively. Results from FAC indicated that jatropha seed oil (JSO) has an approximately 21.6% saturated fat with the main contributors being 14.2% palmitic acid. The physiochemical property results show pH value 8.36, Viscosity 0.52 mm2/s, resistant to corrosion, good stability and a milky colouration. The S/N ratio for main effect plot for JBCF and MBCF stand at 1250 CS, 1.15 FR and 0.65 DOC; and 500 CS, 1.15 FR and 0.65 respectively with R-sq = 85.14% and R-sq(adj) = 71.76% for JBCF Ra and R-sq = 71.24% and R-sq(adj) = 56.35% for JBCF Tw,  compared to R-sq = 84.44% R-sq(adj) = 70.43% is for MBCF Ra, and R-sq = 70.48% and  R-sq(adj)  = 55.92% for MBCF Tw. Conclusively, JBCF exhibit minimal surface roughness, minimal tool wear, minimal environmental biodegradability and overall better performance compare to MBCF which makes it more suitable for turning of AISI 304 Alloy steel and is in good agreement with previous work.

The use of cutting fluids has played a vital role in machining operations in lubrication and cooling. Most cutting fluids are mineral oil-based products that are hazardous to the environment and the worker, cause severe diseases and pollute the environment. In addition, petroleum resources are becoming increasingly unsustainable. Due to environmental and health issues, legislations have been established to ensure that the consumption of mineral oil is reduced. Consequently, researchers are making efforts to replace these mineral oil-based products. Vegetable oils are grasping attention due to their better lubricating properties, ease of availability, biodegradability, low prices, and non-toxicity. In this study, a detailed review and critical analysis are conducted of the research works involving vegetable oils as cutting fluids keeping in view the shortcomings and possible solutions to overcome these drawbacks. The purpose of the review is to emphasise the benefits of vegetable oil-based cutting fluids exhibiting comparable performance to that of mineral oil-based products. In addition, an appropriate selection of non-edible vegetable oil-based cutting fluids along with optimum cutting parameters to avoid a scanty supply of edible oils is also discussed. According to this research, vegetable oils are capable of substituting synthetic cutting fluids, and this option might aid in the successful and cost-efficient implementation of green machining.

This paper proposes a new lubricant environment when MWCNTs was used in MQL for AISI 304L in the turning machine. The effects of dry cutting, MQL cutting, and MWCNTs/MQL were compared to the surface roughness of work pieces, cutting temperature and the tool wear. In the past, the studies have shown that the MQL process can prolong tool life and improve surface accuracy in machining. The purpose of using MWCNTs suspensions is to increase the thermal conductivity of cutting fluid and to reduce the temperature during the cutting and decrease the thermal wear of tool simultaneously. The present study investigated the characterization of the MWCNTs was applied into MQL during the turning process of AISI 304L experimentally. The results showed that the MWCNTs will be a very good additive to MQL, not only with the benefits of improving surface roughness but also with ability of prolonging life of tool by reducing the cutting temperature in turning AISI 304L.

Increased attention on environmental and health impacts by industrial activities forces the manufacturing industry to reduce the mineral oil-based metalworking fluids as a cutting fluid. The advantages of using vegetable oil-based cutting fluids on tool wear and the cutting force have been reported in the literature, but those reporting the effects of their use on the surface finish of the workpiece are still lacking. This mini-review gives an overview of the influence of vegetable oil-based cutting fluids on surface integrity of steel during drilling process. Effect of the different cooling strategies on surface integrity is also presented.

Tribology deals with friction, wear and lubricants. It plays an important role in mechanical field. It finds its major application in industrial and automotive sector, in which this thesis considered the tribology in metal removal industrial sector. In that application, the role of cutting fluid in lathe machining operations have been chosen. One of the most important challenging cases is to minimize the friction in machining of titanium alloys. While machining, the heat should be minimized as low as possible. This thesis deals with the study of cutting fluids in machining of titanium alloys. The problem occurs while using mineral oil as a cutting fluid in machining that it is non-biodegradable in nature and affects the environment while disposing it. This thesis aims to identify the alternate cutting fluids instead of mineral oil, which is to be effective cooling and non-toxic to environment. For that, Machining condition should be controllable by using some grammar rule without affecting the Productivity.

Carbon Fibre Composites (CFC) are commonly used in aerospace, automotive and civil industries to manufacture high performance products which require high strength with low weight. They are usually produced to near net shape, however machining such as milling is frequently performed to achieve dimensional accuracy. This paper presents the effect of using conventional (water-based) and carbon dioxide (CO2) cutting fluids during milling of CFC on cutting forces, temperature and surface roughness in comparison to dry milling. Milling experiments were conducted using uncoated tungsten carbide milling routers at a constant feed rate and depth of cut of 0.025 mm/rev and 5 mm, respectively. Cutting speeds used were 100, 150 and 200 m/min. Cutting forces were measured using a dynamometer, temperatures during milling were measured at the workpiece by thermocouples and surface roughness (Ra) of the milled surfaces were measured using a surface profilometer. Milling with conventional and CO2 cutting fluids resulted in higher cutting forces than dry milling at all cutting speeds used. This was attributed to cooling of the CFC, which retained the strength of polymer matrix during machining. Cutting temperatures were the highest and reached beyond 100°C during dry milling. The use of conventional cutting fluid during milling provided significant cooling to the workpiece, in which cutting temperatures were maintained below 30°C at all cutting speeds used. Cooling the workpiece during milling with CO2 cutting fluid resulted in cutting temperatures within the range of 65–86°C. Even though the application of cutting fluids during milling generated higher cutting forces than dry milling, it produced favourable results in terms of surface finish. The use of cutting fluid during machining CFC is shown to be highly effective in sustaining the strength of CFC materials as a result of low cutting temperature.

This paper reports evaluation of physicochemical and biodegradability properties of selected non edible Nigerian oilseeds as a potential cutting fluid. Oil extraction process was carried on the oilseeds, with physicochemical parameters and biodegradability of the extracts were equally assessed. The established physicochemical parameters were percentage oil yield (5.58-61.8%), specific gravity (0.86-0.94), acidvalue (2.89-18.2 mgKOH/g), iodine value (15.7-104 mg iodine/g), peroxide value (1.35-10.9 mg/g oil), saponification value (173-286 mg KOH/g) and viscosity (37.9-53.1centipoises), while biodegradabilityranged between (50.0-63.8%) in comparison with the mineral oil with values less than 20%. Based on this study, the oil extracts of Caesalpinia bonduc and Calophyllum inophyllum appeared to be the most suitable as potential cutting fluids for further formulation studies and machining trials.
