“…Such an intense thermal effect instigated upon the newly generated surface, sending it into abrupt modes of expansion and contraction, causes deterioration of the surface quality. A 25% reduction in work surface roughness was reported when graphene-dispersed vegetable-oil-based micro-lubrication was applied in the milling of Ti-6Al-4V [17]. An increase in cutting speed was found to reduce the surface roughness when the milling orientation was down-milling.…”

“…Mia et al reported that the use of dual jets of LN 2 is an excellent way to reduce energy consumption and working temperature, as well as to improve work surface quality [15]. In another experimental study, it was reported that the use of liquid CO 2 at a temperature of −79.5 • C in cutting of a nickel-chromium alloy could reduce average surface roughness by [42][43][44][45][46][47][24][25][26][27][16][17][18][19][20][21] wet, and MQL cutting, respectively [16].

Ti-6Al-4V, the most commonly used alloy of titanium, possesses excellent mechanical properties and corrosion resistance, which is the prime reason for the continual rise in its industrial demand worldwide. The extraordinary mechanical properties of the alloy are viewed as a hindrance when it comes to its shaping processes, and the process of milling is no exception to it. The generation of intense heat flux around the cutting zones is an established reason of poor machinability of the alloy and unacceptably low sustainability of its machining. The work presented in this paper attempts to enhance sustainability of milling Ti-6Al-4V by investigating the effects of milling orientation, cutter's helix angle, cutting speed, and the type of cryogenic coolant and lubricant on the sustainability measures, such as tool damage, cutting energy consumption, process cost, milling forces, and work surface roughness. It was found that micro-lubrication is more effective than the two commonly used cryogenic coolants (carbon dioxide snow and liquid nitrogen) in reducing tool wear, work surface roughness, process cost, and energy consumption. Furthermore, down-milling enormously outperformed up-milling with respect to tool wear, work surface quality, and process cost. Likewise, the high levels of cutter's helix angle and cutting speed also proved to be beneficial for milling sustainability.Metals 2020, 10, 258 2 of 25 environmentally [3]. The problem is generally negotiated either by lowering the material removal rates or by applying emulsion-based coolants, neither of which actually offers a sustainable solution.With regard to quashing the intense heat flux around the cutting areas, the application of cryogenic fluids, especially liquid nitrogen (LN 2 ), fares very well. The fluids offer a viable solution because of extremely low operational temperatures, no waste generation, and controllable flow rates. Additionally, application of micro-lubrication, also known as minimum quantity of lubrication (MQL), also proved to be very beneficial in enhancing tool life and improving surface quality in machining of titanium alloys conducted at medium cutting speeds [4,5]. MQL is a near-dry machining method in which a miniscule quantity of lubricating oil is pulverized into a stream of air, and the resulting aerosol is applied onto the cutting areas [6].Although steady progress is being made regarding quantification of the effects of cryogenic coolants with regard to the continuous machining processes, not much effort is being put up concerning interrupted machining processes, such as milling. Cryogenic milling is distinct from continuous machining processes performed under cryogenic environment in the sense that the cutting teeth of a milling tool periodically and rapidly engage and disengage with the work material, leading to cyclic heating (caused by thermal energy released by work material's plastic deformation) and cooling (caused by interaction with the incoming cryogenic fluid) of the cutting edges. Such a course is expected to induce...

“…A reduction in tool wear and an improvement in the quality of the surfaces were achieved due to better cooling of carbon nanotubes at the machining zone. Li et al [15] used graphene nano particles with MQL and revealed a decrease in milling force, temperature and surface roughness with good lubrication delivered through MQL based graphene nano particles in milling TC4 alloys. Wang et al [16] studied the friction mechanism in grinding of Ni based alloy using Al 2 O 3 nano fluids with MQL.…”

Minimum quantity lubrication is an extensively accepted lubrication system owing to its improved heat removal in the machining areas. The purpose of the current study is to examine the effectiveness of graphene based nanofluids in turning on D3 tool steel with minimum quantity lubrication. Experiments were executed with Taguchi's L27 orthogonal matrix array. The effectiveness were examined with the machining parameters under environment (dry condition, flood lubrication and minimum quantity lubrication), cutting speed, feed rate and depth of cut in terms of surface roughness, cutting temperature, tool wear and chip morphology. A technique known as Preference Ranking Organization Method for Enrichment Evaluations were used to determine the imperative parameters governing the responses. The results reveal that graphene nanofluids with minimum quantity lubrication found to be a right substitute in reducing the surface roughness, tool wear and cutting temperature.
