“…23. Shah et al [250] presented the comparison of a newly developed ultra-high voltage electrostatic minimum quantity lubrication (EMQL) using a customized nozzle with the MQL technique as an alternative cooling/lubricating method in turning processes of 15-5 precipitated hardened stainless steel (PHSS). Karagöz et al [251] studied the friction and wear characteristics of graphene and graphene coating deposited by CVD process on Honda GX270 engine (nodular cast iron) piston rings.…”

“…The tool wear was decreased by 38% under EMQL at optimized EV of 20 as compared to MQL for 2400 mm cutting length as shown in figure 16. The high performance was due to improvement in droplet quality and penetrability into the cutting zone [131]. Khan et al (2021) carried out turning of titanium alloy under MQL and liquid nitrogen assisted cryogenic method.…”

Cutting fluids provide cooling at the cutting tool and on the surface of work piece, lubricate the tool-workpiece interface and evacuate chips from the cutting zone in the machining processes. The primary reason for using cutting fluid is to reduce the temperature at cutting zone and friction wear either through cooling or lubrication. To maximize the efficiency of cutting fluids in machining processes the knowledge of machining conditions and cutting fluid types are critically important. However, misemploy of the cutting fluid and non efficient method of disposal can raise health issues and environmental impact. In this paper, an attempt has been made to provide overview of cutting fluids type, cooling techniques and main alternatives as dry machining, cryogenic cooling, minimum quantity lubrication and hybrid cooling minimizing use of cutting fluids. The inclusion of solid lubricants, nano fluids in lubrication/cooling techniques results in increase in the productivity of the process due to reduction in friction and heat at the cutting zone. The cutting parameters and type of tools utilized by various researchers have been summed up and introduced in this paper to provide useful information to various researcher works.

“…So, to achieve all the favorable properties of the NPs in a single run, hybridization is indeed necessary. With the hybridization of two or more different NPs, the resulting NF can have superior rheological and thermo-physical properties with modified heat transfer characteristics compared to mono NF and base fluid [21,172].…”

“…The higher viscosity of the hybrid NF may cause pressure drop (pressure difference between supplied pressure by pump and exit pressure of NF through nozzle) within the MQL system due to the combination of different NPs which ultimately increases the pump power requirements [21].…”

“…The green technology also includes the EMQL which has a combined effect of MQL and electrostatic spraying. EMQL was developed with the aim to reduce the tool wear and consumption of cutting fluid as compared to MQL strategy, which was successfully achieved [21]. Over the past decades, researchers are truly attracted toward the NFs incorporated characterization, preparation, heat transfer, and application of the NF.…”
