“…Using scanning electron microscope and its average was utilised for wear measurement calculation. The criteria considered for average tool wear land width (VB) was 0.3 mm for all the inserts in order to measure the tool life [46]. The flank wear advancement for the different cutting velocities (70, 80, 90 m min −1 ) and its respective feed rates (0.1, 0.15, 0.2 mm rev −1 ) was examined for uncoated cemented carbide insert.…”

Recently Cryogenic cooling has witnessed a significant role in improving efficiency, increasing the quality of machined parts, and developing a techno-economic and eco-friendly acceptable methodology in the machining of components. This study deals with the effect of hardened AISI 4340 steel at 48 HRC against uncoated WC cutting tool analyzed through use of dry, cryogenic liquid nitrogen (Cryo-LN2) and cryogenic liquid carbon dioxide (Cryo-LCO2) cooling environments. The input parameters for this hard turning condition include cutting velocity, feed rate, and depth of cut. A study of the machining performance of cutting temperature, surface roughness, material side flow, flank wear, microhardness, and chips morphology has also been made. The experiment results revealed the effective lowering of the cutting temperature, better surface roughness and reduces flank wear for LCO2 and LN2 coolant by cryogenic cooling against dry cutting condition. Compared to dry and cryogenic LCO2 cutting environments, the machined zone of a cryogenic LN2 exhibited the highest microhardness value. The main reason for this was the decrease in the thermal softening effect. Overall, the performance of the cryogenic LN2 environment condition was effective and efficient in the turning process compared to dry and cryogenic LCO2.

“…Eltaggaz et al [182] showed that Al 2 O 3 nanoparticles enhanced the lubricity of vegetable oil in MQL application and this improvement can be attributed to ball bearing effect, tribofilm formation, mending effect, and polishing effect. Babu et al [183] observed the chip morphology under application of nanofluids concluded that it improved the lubrication ability; hence, decrease the temperature and chip reduction coefficient. Das et al [167] and Lalatendu Dash et al [184] stated that nano-fluid based MQL method favours the various chip morphological characteristics as well lesser residual stress; owing to its better wettability and spreading ability as compare to simple one.…”

In this review work, various conventional cutting fluids and their application methods have been discussed, which serve different functions such as cooling, lubrication, cleaning, and corrosion protection during the machining process. According to the available research, issues associated with the conventional ones have beenidentified concerning sustainability metrics, i.e., economic, environmental, and social dimensions. These issues necessitated shifting toward sustainable alternatives. All such alternatives have been reviewed thoroughly, which are presently practiced in the machining of steels as a workpiece. It can be concluded that these sustainable methods, i.e., dry cutting, minimum quantity cooling and lubrication, cryogenic lubricant, gas-based coolant, solid lubricant, etc, provide better machinability performance as compared to conventional ones. However, there is a need oftrade-off analysis between cost-effectiveness and sustainability for various combinations of cutting fluids and their application methods. The last section summarizes the review study and recommends prospects based on the demands and challenges ahead. Further, it can be concluded that knowledge of the cutting fluid types and their application methods with detailed efficiency and energy consumption models are critically important to make them commercially viable.

“…While using a nano-cutting fluid, the oil-penetrated particles stick to the machined surface and encourage plastic to flow on the chip in reverse. Consequently, MQL technology greatly enhances machinability, and when the cutting fluid nozzle is projected on the tool's flank [6] surface, a greater amount of cutting fluid can penetrate the tool [7,8].…”

The minimum quantity lubrication (MQL) approach is used for improving tool life at a low cost, and it is environmentally friendly. When compared to traditional flood cooling technology, the flow rate in MQL is thought to be 10,000 times lower. The workpiece’s surface smoothness is enhanced by continuous chip formation during turning, but because the tool is always in touch with the chip, a crater wear zone is formed on the rake face due to high friction and thermal stress. While adding nanoparticles to MQL enhances cutting performance, a high concentration of these nanoparticles causes burr adhesion and decreased chip evacuation capability due to the agglomeration of nanoparticles, which affects the surface finish of the workpiece. A novel “coconut-oil-based SiC–MWCNT nano-cutting fluid for a CBN insert cutting tool” is proposed in this approach to overcome these issues. Silicon carbide (SiC) and multi-walled carbon nanotubes (MWCNTs) are added to coconut oil with an appropriate volume fraction for better lubrication. The thermal properties of the proposed nano-cutting fluid are compared with those of some existing nano MQL cutting fluids, and it was found that the MQL cutting fluid under consideration exhibits an elevated thermal conductivity and convective heat transfer coefficient that efficiently reduce tool temperature and improve tool life. The comparative study between the Finite Element Simulation using computational fluid dynamics (CFD) predicted variation in tool temperature and the corresponding experimental values revealed a remarkable alignment with a marginal error ranging from 1.27% to 3.44%.
