“…If the R 2 and R 2 (Adj) results are close to one, then the developed models are said to be fit to the experimental data [64,65]. In the current study, Minitab 17 software was used to generate the linear regression equations under both cooling scenarios as displayed in Equations ( 1)- (10). The estimated R 2 and R 2 (Adj) results for each model are traced to be nearer to one; thus, all the generated models are fit to the experimental results.…”

This study investigates the performance comparison of machining of UNS S32750 super-duplex stainless steel under single- and double-nozzle pulse mode minimum quantity lubrication (MQL) conditions. The pulse mode MQL system delivers lubricant pulses at specific intervals. The Taguchi L9 design, with three factors and their three levels, was taken to perform the CNC turning experiments under both single-nozzle and double-nozzle MQL cooling environments. The surface roughness (Ra), tool-flank wear (VB), tool-flank temperature (Tf), power consumption (Pc), and material removal rate (MRR) are evaluated and compared as performance indicators. In comparison to single-nozzle MQL, the responses of Ra, VB, Tf, and Pc were found to be decreased by 11.16%, 21.24%, 7.07%, and 3.16% under double-nozzle conditions, respectively, whereas MRR was found to be 18.37% higher under double-nozzle conditions. The MQL pulse time was found to be an important variable that affects Ra, VB, Tf, and MRR significantly. Under both cooling scenarios, common wears such as abrasion, built-up edges, adhesion, and notch wear are detected. Furthermore, the Pugh matrix-based sustainability evaluation results revealed that the double-nozzle MQL technique was superior to single-nozzle MQL, achieving improved sustainability for machining super-duplex stainless steel.

“…The mist has the capability to infiltrate the cutting zone, hence mitigating the generation of elevated temperatures. The conducted experiments aimed to compare the outcomes with MQL and revealed that MQL resulted in a reduction in tool wear (Sultana and Dhar, 2022). Szczotkarz et al (2020) conducted a study to examine the advantages of using the MQL and MQCL techniques alongside the extreme pressure and anti-wear (EP/AW) approach.…”

To maximize production while reducing environmental effect, the machining industry is always looking for new, sustainable, and cost feasible ways. One approach that shows promise in this area is Minimum Quantity Lubrication (MQL). The MQL approach is briefly reviewed in this work with an emphasis on its use in machining. At the beginning of the study, a basic introduction of the MQL method is given, and then its effect on tool wear, surface roughness, cutting temperature and the energy consumption is reviewed. In brief, this paper discusses MQL's lubrication methods, benefits, drawbacks, and applications in different machining operations. The outcomes demonstrated that the MQL efficacy is also affected by tool material, workpiece material, cutting conditions, and lubricant type. Therefore, it is worth to mention that this review emphasizes MQL's sustainability in machining lubrication. By balancing its pros and cons, this study hopes to help readers understand MQL and its potential to optimize machining operations in many industries.

Hard turning technology has received much attention and is becoming an alternative to the grinding process due to its high productivity, suitability for complex profiles, reduced use of cutting oil, and good surface quality. However, very severe cutting zone conditions such as very high friction, cutting forces and temperature in the cutting zone require special cutting tool materials and limited cutting modes. MQL and MQCL methods with nano-cutting oils are used to support hard-turning processes that improve cutting efficiency while ensuring environmentally friendly properties. Currently, the selection of suitable lubrication methods, base oil, and nanoparticle type is an issue that needs to be researched. Moreover, the trend of researching suitable lubricating technology so that conventional cutting tools (carbide inserts) can be used in hard machining is also an interesting research trend. This paper focuses on analyzing and evaluating the machining efficiency when turning 90CrSi (60 -62 HRC) steel using MQL and MQCL by adding Al2O3 and MoS2 nanoparticles to the base liquid (soybean oil and emulsion). Analysis of variance (ANOVA) was used to evaluate the influence of the MQL and MQCL parameters on the total cutting force. At the same time, the trend and influence of the parameters MQL and MQCL on the total cutting force are also analyzed. The obtained results showed that the uses of MQL with nanofluid made from MoS2 and emulsion or MQCL with nanofluid made from Al2O3 and soybean can significantly reduce the total cutting force. The obtained results showed that the machinability of carbide inserts was improved and the highest machinable hardness was increased from 35 HRC to 60 ÷ 62 HRC (rising by approximately 75%) by using the nanofluid MQL and MQCL methods. Furthermore, MQCL gives better performance than MQL, and the MoS2 nanofluid exhibits a better result in terms of the total cutting force values than the Al2O3 nanofluid. From these results, technical guidance will be provided for further studies using Al2O3, MoS2 or hybrid Al2O3/MoS2 nanofluids for MQL and MQCL methods, as well as their application in machining practice.
