“…Jurkovic et al [26] studied surface roughness (Ra), cutting force (F c ), and tool lifetime (T) in high-speed turning, by applying three machine learning methods for the prediction of independent output cutting parameters. Mia et al [27] studied the effect of three sustainable techniques and the traditional flood cooling system, on prominent machining indices such as cutting temperature, surface roughness, chip characteristics, and tool wear in plain turned hardened AISI 1060 steel. However, none of the above studies [19][20][21][22][23][24][25][26][27] included models for predicting surface roughness in the turning of Alloy 6061.…”

Aluminum Alloy 6061 components are frequently manufactured for various industries-aeronautics, yachting, and optical instruments-due to their excellent physical and mechanical properties, including corrosion resistance. There is little research on the mechanical tooling of AA6061 and none on its structure and properties and their effects on surface roughness after finish turning. The objective of this comprehensive study is, therefore, to ascertain the effects of both the modern method of hardening AA6061 shafts and the finish turning conditions on surface roughness, Ra, and the minimum machining time for unit-volume removal, T m , while also establishing the cost price of processing one part, C. The hardening methods improved both the physical and the mechanical material properties processed with 2, 4, and 6 passes of equal channel angular pressing (ECAP) at room temperature, using an ECAP-matrix with a channel angle of 90 •. The reference workpiece sample was a hot extruded chip under an extrusion ratio (ER) of 5.2 at an extrusion temperature of 500 • C (ET = 500 • C). The following results were obtained: grain size in ECAP-6 decreased from 15.9 to 2.46 µm, increasing both microhardness from 41 Vickers hardness value (HV) to 110 HV and ultimate tensile strength from 132.4 to 403 MPa. The largest decrease in surface roughness, Ra-70%, was obtained turning a workpiece treated with ECAP-6. The multicriteria optimization was computed in a multilayer perceptron-based artificial neural network that yielded the following optimum values: the minimal length of the three-dimensional estimates vector with the coordinates Ra = 0.800 µm, T m = 0.341 min/cm 3 , and C = 6.955 $ corresponded to the optimal finish turning conditions: cutting speed v c = 200 m/min, depth of cut a p = 0.2 mm, and feed per revolution f r = 0.103 mm/rev (ET-500 extrusion without hardening).

“…In results, they manifested that at 720 rpm spindle speed, commercial oil gave minimum machining responses. Mia et al [52] adopted olive oil as a green biodegradable coolant in turning of hardened steel as the medium of MQL. They have assessed the performance with respect to the surface quality and temperature of the cutting zone.…”

In modern days, the conception of sustainability has progressively advanced and has begun receiving global interest. Thus, sustainability is an imperative idea in modern research. Considering the recent trend, this review paper presents a summary of the previously published research articles on minimum quantity lubrication (MQL) assisted machining. The requirement to stir towards sustainability motivated the researchers to revise the effects of substitute lubrication methods on the machining. Conventional lubri-cooling agents are still extensively employed when machining of engineering alloys, but the majority of the recent papers have depicted that the utilization of vegetable oil, nanofluids, and nanoplatelets in MQL system confers superior machining performances as compared to conventional lubrication technology. In actual, the definite principle of this manuscript is to reexamine modern advancements in the MQL technique and also explore the benefits of the vegetable oil and nanofluid as a lubricant. In brief, this paper is a testimony to the advancing capabilities of eco-friendly MQL technique which is a viable alternative to the flood lubrication technology, and the outcomes of this review work can be contemplated as a movement towards sustainable machining.

“…may be used as solid lubricants [28,33]. A second alternative is minimum quantity lubrication (MQL), where the air and grinding fluid are mixed in a specially designed nozzle and accurately directed into the grinding zone [21][22][23]34]. Comparing to the conventional flood cooling, the flow rate of the GF is about three or four orders of magnitude lower and amounts to 50-500 ml/h.…”

In the paper, the results of experimental studies related with determination of the influence of the supply of a grinding fluid (GF) doped with powdered graphite and MoS 2 into the machining zone with the minimum quantity cooling (MQC) method on the course and results of the reciprocating internal cylindrical grinding of rings made from Inconel® alloy 718 have been presented. As a grinding fluid, water aerosols were used. The aerosols delivered the following into the grinding zone: water slurry MoS 2 with a concentration of 30 g/dm 3 , water slurry of graphite with a concentration of 30 g/dm 3 , 5% water solution of Syntilo RHS oil and pure demineralized water. The obtained results of carried out experiments showed that the most favorable conditions of grinding wheel operation were obtained when MQC-based delivering an aerosol of water slurry made from demineralized water doped with MoS 2 and graphite with a minimum flow rate and when delivering an aerosol of 5% water slurry of Syntilo RHS oil. It was proved that doping GF with powdered MoS 2 and graphite, with delivery in the form of an aerosol with a minimum flow rate, has a substantial influence on the intensity of clogging grinding wheel active surface (GWAS). Additionally, it has been demonstrated that the solid grease MoS 2 and graphite particles reached the area of contact of the GWAS and the machined surface effectively, actively influencing its tribological conditions of the grinding process.
