“…Therefore, the shape of the chips produced with cryogenic cooling changes from long and leafy chips for dry and wet cooling to short lamellar and blocky chips, whose generation requires less specific energy and therefore reduces the grinding forces. The close relation between the material separation mechanisms and the process forces was also shown in a study on AISI D3 steel [8]. However, all studies on the influence of cryogenic cooling on the produced chips and the ground surface are carried out by collecting the chips and the analysis of the surface after the finished grinding process.…”

The combination of highly heat-conducting cubic boron nitride (cBN) grains in a bronze-bonded grinding wheel with the cryogenic temperatures of a gaseous carbon dioxide cooling has the potential to greatly reduce the thermal load during the grinding process. This decreases the risk of thermal damage or heat-induced property changes in the workpiece. In this study, the influence of this combination on the material separation while grinding 20MnCrS5 steel is investigated using a quick-stop device, compared to a conventional oil-based cooling. The contact zone analysis shows primarily grooving grain tracks while grinding with oil cooling. However, under the influence of cryogenic cooling, mostly grain tracks from plowing grains were found in the contact area as a result of the increased friction between the grains and the workpiece material. This shows that material separation with cryogenic cooling is more efficient compared to the oil-cooled process.

“…The wedge gap is formed between grinding wheel and workpiece in plane grinding, and the nozzle must be at a certain angle with the workpiece to spray the coolinglubrication medium into the grinding area effectively. The conventional method sprays the cooling-lubrication medium into the grinding wheel-workpiece interface using an external spraying device [91][92][93]. However, an "air barrier layer" is formed in the wedge-shaped area due to the high-speed rotation of the grinding wheel, which prevents the cooling-lubrication medium from entering the grinding zone [94].…”

“…Coating a layer of special material on the tool surface is mainly used to improve the cutting performance of tools considering material technology innovation. The usage amount of coated tools in cutting accounts for approximately 68% of all types of tools [91]. Tool life, which is closely related to tool wear mechanism, is an important index to determine machining performance.…”

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.

“…Among others, surface roughness has always been the ultimate factor to be controlled. Although thermal analysis of grinding is complicated, this field of research has been improved due to the studies by [ 9 ], who proposed a comprehensive thermal model of grinding that has been widely used in grinding problems since then. His study was later on republished in the form of a book [ 10 ].…”
