“…The stability of cutting fluid is very important for reliable functioning. The stability of cutting fluids was studied by conducting a temperature test and mechanical test [41]. In the temperature test, the sample cutting fluids were kept at room temperature and their appearance, color, consistency, and homogeneity were investigated.…”

In spite of better performance, the disposal of used petroleum-based cutting fluids threatens our environment. Thus, it is essential to develop eco-friendly cutting fluids for performing machining operations in industries. The main contribution of this paper is to develop an eco-friendly cutting fluid for the plain turning of AISI 1010 steel which is used in the automotive industry. In the present work, boric acid (H3BO3) was mixed with the neem seed. Neem seed oil is easily available in many countries including India. The effectiveness of the proposed cutting fluid was evaluated by conducting different tests as per the standards. The mean biodegradability value of the developed cutting fluid is 97% which is better than other cutting fluids. The average cutting force required by the proposed cutting fluid is only 127.2 N which is much less than the cutting force requirements of dry machining and conventional cutting fluids. The average surface roughness of the machined component using the proposed cutting fluid is 122.9 µm. The mean flank wear of the tool is only 289 µm. The flash point of the proposed cutting fluids is more than 250 °C which is better than the conventional cutting fluids. The fire point of the neem oil-based cutting fluids is 300 °C. The results of the stability test and the microhardness test revealed the effectiveness of the proposed cutting fluids. The results obtained in this work are superior to several other cutting fluids reported in the existing literature. Hence, it is suggested to replace the existing petroleum-based metal cutting fluid with this eco-friendly cutting fluid in the automotive industry in Hosur, India.

“…Due to the widespread and extensive use of cooling lubricants, sustainability issues are of particular importance. While eco-friendly alternatives to conventional cooling lubricants are currently being investigated [1][2][3], the extension of the service lives of MWFs is another important strategy for improving sustainability. According to DIN 51385, lubricants can be classified by their various fields of application and by composition [4].…”

Metalworking fluids (MWFs) are widely used to cool and lubricate metal workpieces during processing to reduce heat and friction. Extending a MWF’s service life is of importance from both economical and ecological points of view. Knowledge about the effects of processing conditions on the aging behavior and reliable analytical procedures are required to properly characterize the aging phenomena. While so far no quantitative estimations of ageing effects on MWFs have been described in the literature other than univariate ones based on single parameter measurements, in the present study we present a simple spectroscopy-based set-up for the simultaneous monitoring of three quality parameters of MWF and a mathematical model relating them to the most influential process factors relevant during use. For this purpose, the effects of MWF concentration, pH and nitrite concentration on the droplet size during aging were investigated by means of a response surface modelling approach. Systematically varied model MWF fluids were characterized using simultaneous measurements of absorption coefficients µa and effective scattering coefficients µ’s. Droplet size was determined via dynamic light scattering (DLS) measurements. Droplet size showed non-linear dependence on MWF concentration and pH, but the nitrite concentration had no significant effect. pH and MWF concentration showed a strong synergistic effect, which indicates that MWF aging is a rather complex process. The observed effects were similar for the DLS and the µ’s values, which shows the comparability of the methodologies. The correlations of the methods were R2c = 0.928 and R2P = 0.927, as calculated by a partial least squares regression (PLS-R) model. Furthermore, using µa, it was possible to generate a predictive PLS-R model for MWF concentration (R2c = 0.890, R2P = 0.924). Simultaneous determination of the pH based on the µ’s is possible with good accuracy (R²c = 0.803, R²P = 0.732). With prior knowledge of the MWF concentration using the µa-PLS-R model, the predictive capability of the µ’s-PLS-R model for pH was refined (10 wt%: R²c = 0.998, R²p = 0.997). This highlights the relevance of the combined measurement of µa and µ’s. Recognizing the synergistic nature of the effects of MWF concentration and pH on the droplet size is an important prerequisite for extending the service life of an MWF in the metalworking industry. The presented method can be applied as an in-process analytical tool that allows one to compensate for ageing effects during use of the MWF by taking appropriate corrective measures, such as pH correction or adjustment of concentration.

Although the manufacturing industry has improved the quality of processing, optimization and upgrading must be performed to meet the requirements of global sustainable development. Sustainable production is considered to be a favorable strategy for achieving machining upgrades characterized by high quality, high efficiency, energy savings, and emission reduction. Sustainable production has aroused widespread interest, but only a few scholars have studied the sustainability of machining from multiple dimensions. The sustainability of machining must be investigated multidimensionally and accurately. Thus, this study explores the sustainability of machining from the aspects of equipment, process, and strategy. In particular, the equipment, process, and strategy of sustainable machining are systematically analyzed and integrated into a research framework. Then, this study analyzes sustainable machining-oriented machining equipment from the aspects of machine tools, cutting tools, and materials such as cutting fluid. Machining processes are explored as important links of sustainable machining from the aspects of dry cutting, microlubrication, microcutting, low-temperature cutting, and multidirectional cutting. The strategies for sustainable machining are also analyzed from the aspects of energy-saving control, machining simulation, and process optimization of machine tools. Finally, opportunities and challenges, including policies and regulations toward sustainable machining, are discussed. This study is expected to offer prospects for sustainable machining development and strategies for implementing sustainable machining.
