Cutting fluids are important elements of manufacturing industries and are used in large quantities. But its use poses a serious health issue to the surrounding people working in its atmosphere. Hence, the disposal should be only after neutralization thereby protecting worker and aquatic life. This leads to select an optimal alternative that is not only environmentally friendly but also safe for human beings and aquatic life. Further, it should also perform at par with the mineral oil-based cutting fluid. In the present research, a framework has been proposed to assist the decision-makers in the selection and evaluation of lubricant by the Analytical hierarchical process (AHP) and VIKOR method. In the proposed research three cutting fluids i.e. Neem oil with 5% emulsifier, Neem oil with 10% emulsifier, and a conventional mineral oil-based cutting fluid have been considered as alternatives. These have been evaluated on the basis of different significant parameters like the temperature at the tooltip, surface roughness, and tool wear. The basic aim of this paper is to present the logical selection process of a cutting fluid as well as to show that ranking or choice of cutting fluid may also change if the priority of the parameter is changed.

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.

The study investigated the effects cutting fluids on tool wearing on high speed steel (HSS) using mild steel workpiece for teaching machining operation. Two specific objectives guided the study, two corresponding research questions were poised and two null hypotheses were formulated. The theoretical frame work for the study was hinged on experiential learning theory as propounded by Rogers (1969). The growing demand for biodegradable materials has opened an avenue for using vegetable oils such as neem seed oil, castor oil and water melon seed oil as an alternative to conventional cutting fluids. In this study, some aspects of the turning process on mild steel using HSS cutting tool at variety of spindle speed, feed rate and constant depth of cut were observed using neem seed oil, soluble oil and straight oil in comparison. The data collected from the study was analyzed using mean and analysis of variance (ANOVA). The decision rule was that, the smaller the mean value obtained the more effective the cutting fluid and the higher the mean value, the less effective the cutting fluid. The hypotheses were tested at α=0.05 significance level using analysis of variance (ANOVA). The findings of the study revealed that soluble oil is more effective in reducing tool wearing than neem oil and straight oil at variety of feed rates and spindle speeds during machining operation. Also there is no significant difference in the mean readings of tool wearing when using neem oil, soluble oil, and straight oil as cutting fluid. It was therefore recommended that machinists should be encouraged to use soluble oil which has greater advantage over neem and straight oils in machining operations

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.

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.

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.

PurposeThis study aims to determine the properties of a new non-toxic cutting fluid and compared with cutting fluid based on mineral oil.Design/methodology/approachThe tool wear was measured under dry and wet cutting conditions. The non-toxic cutting fluid was compared with cutting fluid based on mineral oil. The experiments were carried out using CTX 310 ECO numerical control lathe. The wear of the cutting tools was measured by means of stereo zoom microscopy (SX80), while the elements were identified through scanning electron microscopy (JSM 7100F). The workpiece surface texture was studied using a Talysurf CCI Lite non-contact 3D profiler. The contact wetting angle was established with a KSV CAM 100 tester.FindingsThe non-toxic cutting fluid has reached comparable coefficient of friction with a coolant containing mineral oil. The use of the non-toxic cutting fluid with low foaming tendency resulted in lower wear.Practical implicationsMachining processes require that cutting fluids be applied to reduce the tool wear and improve the quality of the workpiece surface. Cutting fluids serve numerous purposes such as they act as coolants and lubricants, remove chips and temporarily prevent corrosion of the product.Originality/valueThe investigations discussed in this paper have contributed to the development of non-toxic and environmentally friendly manufacturing because of the use of cutting fluid containing zinc aspartate and its comparison with commonly used cutting fluid.

Airport projects can have a significant impact on sustainable development. In Germany, as in many other developed countries, airport development is confronting a dilemma because, on the one hand, airports are important infrastructural components and, on the other hand, airport development faces strong resistance from local populations and interest groups. Thus, uncertainties and long time periods, up to 20 years from the beginning of planning to breaking ground, are quite normal. To ease airport development in Germany, administrative procedures and public participation were enhanced. Nevertheless, even with improved public participation, siting decisions in the case of Berlin Brandenburg Airport (BER) were lengthy as usual and remain controversial today due to the selection of Schönefeld as the site. Against this background, it seems that public participation in the case of the BER site selection did not particularly deliver the hoped-for results, but why? To answer this question, Creighton’s principles of effective public participation are employed as benchmarks. Moreover, the benchmarking indicates that public participation was not effectively applied. Thus, the possible benefits of public participation could not or could only be partly reaped. Furthermore, from a broader politico-economic perspective, the analysis exposes that public participation was just “a small cog in the machine” of the BER site selection process. It seems that other factors had a more substantial influence on the siting decision than public participation and led decision makers, in addition to regular challenges, into a predicament that might have made Schönefeld the only possible siting solution. In this context, different counterfactual scenarios are discussed to show under which circumstances other outcomes might have occurred regarding the BER site selection.

This paper proposes an optimization strategy for the best selection process of suppliers. Based on recent literature reviews, the paper assumes a selection of commonly used variables for selecting suppliers, and using Logistic regression algorithm technique, to build a model of optimization that learns from customer’s requirements and supplier’s data, and then make predictions and recommendations for best suppliers. The supplier selection process can quickly at times, turn into a complex task for decision-makers, to dealing with the growing number of supplier base list. But Logistics regression technique makes the process easier in the ability to efficiently fetch customer’s requirements with the entire supplier base list and determine by predicting a list of potential suppliers meeting the actual requirements. The selected suppliers make up the recommendation list for the best suppliers for the requirements. And finally, graphical representations are given to showcase the framework analysis, variable selection, and other illustrations about the model analysis
