“…Before the microhardness measurements, ground workpieces were sanded employing silicon carbide sandpapers with 220, 320, 600, 800, 1000, and 1200 mesh and then polished using alumina paste of 0.1 µm size (metallography technique). Although the choice of carrying out the polishing process before measuring microhardness was due to in other works on grinding, the polishing process was also used successfully before the measurement of microhardness, as in a study developed by Silva et al [28], Moraes et al [29], Srivastava et al [30], Javaroni et al [31], and Garcia et al [32]. The microhardness was evaluated using a SHIMADZU HMV-2 series hardness tester with a Vickers penetrator (Barueri, Brazil).…”

In most grinding processes, the use of cutting fluid is required, and research has been carried out to reduce the amount of fluid used due to costs and environmental impacts. However, such a reduction of fluid can result in thermal damage to the machined component because the amount of cutting fluid may not be sufficient to lubricate and cool the system. One way of improving the cutting fluid properties is to add micro or nanoparticles of solid lubricants. This paper aims to evaluate the performance of multilayer graphene platelets dispersed in cutting fluid and applied through the technique of minimum quantity of lubrication (MQL) during the peripheral surface grinding of SAE 52100 hardened steel. In this sense, the influence of these solid particles with respect to the surface and sub-surface integrity of the machined components was analyzed, performing the roughness and microhardness measurement and analyzing the ground surfaces. The results showed that the cooling–lubrication conditions employing graphene could obtain smaller roughness values and decreases of microhardness in relation to the reference value and components with better surface texture compared to the conventional MQL technique without solid particles.

“…Thus, scholars proposed the near-dry cooling-lubrication technology of CA + MQL, which is a combination of CA (−10 °C to −60 °C) and MQL. Micro lubricating oil is atomized into micron-sized particles by high pressure and cryogenic gas, and sprayed to the cutting area at a high speed [53]. The temperature difference between the CA and cutting zone can enhance heat transfer, and the high-speed airflow can lead the heat away from the cutting zone.…”

Cutting fluid plays a cooling-lubrication role in the cutting of metal materials. However, the substantial usage of cutting fluid in traditional flood machining seriously pollutes the environment and threatens the health of workers. Environmental machining technologies, such as dry cutting, minimum quantity lubrication (MQL), and cryogenic cooling technology, have been used as substitute for flood machining. However, the insufficient cooling capacity of MQL with normal-temperature compressed gas and the lack of lubricating performance of cryogenic cooling technology limit their industrial application. The technical bottleneck of mechanical—thermal damage of difficult-to-cut materials in aerospace and other fields can be solved by combining cryogenic medium and MQL. The latest progress of cryogenic minimum quantity lubrication (CMQL) technology is reviewed in this paper, and the key scientific issues in the research achievements of CMQL are clarified. First, the application forms and process characteristics of CMQL devices in turning, milling, and grinding are systematically summarized from traditional settings to innovative design. Second, the cooling-lubrication mechanism of CMQL and its influence mechanism on material hardness, cutting force, tool wear, and workpiece surface quality in cutting are extensively revealed. The effects of CMQL are systematically analyzed based on its mechanism and application form. Results show that the application effect of CMQL is better than that of cryogenic technology or MQL alone. Finally, the prospect, which provides basis and support for engineering application and development of CMQL technology, is introduced considering the limitations of CMQL.

“…Many researchers (Choudhury and Dhar [ 106 ], Dhar et al [ 96 ], Saha et al [ 107 ], Uysal et al [ 108 ], Garcia et al [ 68 ], and Gupta et al [ 109 ]) conducted experimental studies and concluded that the application of MQL in machining of steel were able to improve final surface roughness effectively. Dhar et al [ 53 ] investigated the influence of MQL on the cutting temperature, chip formation, and dimensional accuracy in turning of AISI-1040 steel.…”

This paper reviews recent progress and applications of usage of cutting fluids in conventional machining processes. In addition to reviewing the various conventional and advanced cooling techniques during machining, the paper also discusses the use of minimum quantity lubrication (MQL) in several types on metals such as steel, aluminum, alloy, and titanium alloys. Due to the toxicity of conventional cutting fluid resulting in ecological problems, the demand for environmentally friendly cutting fluid is rising. Therefore, natural vegetable oil is chosen as potential replacement as an environmentally friendly cutting fluid which fulfills the important aspects of biodegradability and sustainability. Application of vegetable oil-based cutting fluids under MQL techniques are also discussed. Moreover, the potential of palm oil as biodegradable and environmentally friendly natural vegetable oil-based metal-working fluids in MQL are reviewed.
