“…(2) Dry cutting of aluminum: As we all know, aluminum has low hardness and good plasticity, which makes the processing difficulty of aluminum not lower than that of other high-hardness materials [15] . High-speed machining requires the choice of high cutting data and more energy-efficient lubrication methods.…”

“…To improve the hardness of WS 2 -based composite films, an effective strategy is to alternately deposit or co-deposit WS 2 and a hard metal nitride phase, such as TiSiN [10], TiN [11,12], or TiAlSiN [13], to form hard lubricant thin films. However, the preparation of metal nitride hard coatings often requires high temperatures.…”

Magnetron-sputtered WS2 composite thin films are solid lubricants with excellent performances. However, the low hardness of the WS2 thin films necessitates the further improvement of their wear resistance. For this purpose, an effective strategy is to alternately deposit or code posit WS2 and a hard phase, such as TiB2, to form hard lubricant thin films. Herein, a TiB2 thin film was prepared under the same conditions as those used for depositing the WS2 thin film with a dense structure and excellent tribological properties. Because of the high deposition energy of high-power impulse magnetron sputtering (HiPIMS), the TiB2 thin film possesses a dense structure and leather-like flat surface (hardness = 24.17 GPa). The friction coefficient of the film under different loads ranges between 0.6 and 0.8. The wear rate of the thin film increases with load, mainly because of fatigue wear and abrasive wear. Under high loads, obvious furrow-like wear marks are observed. At different sliding frequencies, except 8 Hz, the friction coefficient of the film ranges from 0.6 to 0.8. The main wear mode is fatigue wear, particularly at increasing sliding frequencies. Although the film possesses a relatively high friction coefficient, its wear resistance is excellent (minimum wear rate = 1.96 × 10−6 mm3/(N·m)).

“…Reduced tool-chip contact duration was the main factor responsible for cutting tools performing better. The T2, T3, and T4 tools' tool life was increased by 35%, 29%, and 43%, respectively [7]. Ranjan et al 2022 investigated how variations in the rake and ank faced bio-inspired crescent textured tool characteristics, such as radius, edge distance, depth, and centre distance, affected the cutting performance of di cult to cut martensitic AISI 420 steel.…”

To improve tribological properties in the tool chip contact zone, coated carbide tool insert surfaces are nano-finished using magnetorheological fluid (MRF) with diamond abrasives. In order to polish surfaces without significantly increasing the danger of damage to the tool's cutting blades, the configuration of the magnetic particle chain feeding the abrasives is essential. The CNMG 120408-F3M IC807 ISCAR make coated carbide inserts as received have an average surface roughness of 90 nm on the rake face and 110 nm on the flank surface. This unique MRF-assisted tool finishing process results in surface roughness of the tool inserts of less than 30 nm on the flank and less than 48 nm on the rake face. Turning super duplex stainless steel under dry cutting circumstances encourages the use of environmentally friendly machining methods. The machinability characteristics of the nano finished inserts are investigated in the dry turning of S32750 super duplex stainless steel based on surface roughness, cutting force, and tool wear. Compared to unprocessed tools, MRF-assisted nano finished tools demonstrated up to 30% longer tool life spans. The average tool life for nano-polished inserts is 27 mins, compared to 19 mins for unprocessed inserts for a tool life criterion of max. flank wear land, VB = 500 µm, at a cutting speed of 108 m/min, a feed rate of 0.212 mm/rev, and a depth of cut of 1.2 mm. Turning an S32750 super duplex stainless steel material has also seen an 18% reduction in cutting forces attributed to the use of nano polished inserts that also provide excellent lubricity. In terms of cutting forces, flank wear, and surface roughness, the results show that nano polished inserts perform better than conventional inserts.
