“…As far as feed rate (ƒ z ) is concerned, the effect of ƒ z is an anticipated behavior which is consistent with other studies [5,19]. In a previous study, Zahoor et al [5] found that the machine spindle-force vibrations and ƒ z are the most effective parameters for R a during the milling of AISI P20 tool steel.…”

“…To compensate for the inadequacy of the cooling methods, the use of advanced cutting fluids such as vegetable and modified vegetable oil ester-based biodegradable fluids, solid lubricants and nanoparticles [17][18][19] are studied. In context of the use of advanced cutting fluids, Pereira et al [17] apply different biodegradable oils with MQL during the milling of Inconel 718.…”

Flood cooling is a typical strategy used in the machining of difficult-to-cut materials where high temperatures are produced. Several environmental and health concerns are associated with the cutting fluids employed during this technique. Vegetable oil-based fluids appear to be the best substitute to conventional mineral/synthetic oils due to their environmentally friendly, biodegradable, renewable, and less toxic properties. Therefore, this paper attempts to establish an environmentally conscious, flood-cooling alternative through replacing conventional fluids with a synthetic vegetable ester-based (Mecagreen 450) biodegradable oil to investigate the machinability aspects of Inconel 718. In addition to the cooling environment, cutting speed ( s), feed per tooth (ƒ z), and axial depth of cut (a p) have been used as control variables. A Taguchi L 9 array has been selected for the design of experiments (DOE). Parametric effects and microscopic analyses have been carried out to investigate the three response parameters, i.e., surface roughness (R a), tool wear, and material removal rate (MRR). Tool wear analysis is further supplemented with scanning electron microscopy (SEM) and energy-dispersive spectroscopy (EDS).

“…The massive reduction of lubricant consumption over conventional and high-pressure machining systems is the key feature of this technology. Furthermore, adequate lubrication, as well as improvement in cutting performances, has been observed by its adoption [121][122][123][124][125][126][127][128].…”

Inconel 718 is the most used nickel superalloys with applications in aerospace, oil and gas, nuclear, and chemical industries. It is mostly used for safety-critical components where the condition of the surface is a significant concern. The combination of mechanical, thermal, and chemical properties of Inconel 718 has made it a difficult-to-machine material. Despite recent advances in machining Inconel 718, achieving desired surface integrity with prescribed properties is still not possible. Different machining environments have been investigated for improving the machinability of Inconel 718 and enhance the surface integrity of machined components. This paper provides a new investigation and classification into recent advances in the machining of Inconel 718 regarding surface integrity, mostly concentrated on turning applications. The major findings and conclusions provide a critique of the state-of-the-art in machining environments for Inconel 718 together with future directions for research. Surface integrity has been evaluated in terms of surface topology as well as mechanical and microstructural properties. The impact of various cooling and lubrication methods has been investigated. It has been found that surface integrity is affected by the thermomechanical conditions at the cutting zone which are influenced by the cutting parameters, cutting tool, tool wear, and cooling/lubrication condition. The current technologies are incapable of delivering both productivity and sustainability while meeting surface integrity requirements for machining Inconel 718. High-pressure cooling has shown the potential to enhance tool wear at the expense of higher power consumption.

“…To minimize the excessive coolant, MQL is the most eminent technique for supplying minimum quantity of coolant to exact cutting area at high pressure with certain flow rate (5-10mL/min) in the form of mist generation (Krishna and Rao, 2008). Marques et al, (2016) reported the enhancement in surface integrity of workpiece and life of cutting tool with the inclusion of graphite nanoparticle in neat oil compared to MoS2 (Molybdenum di sulfide) in turning of Inconel 718 using MQL mode. Apart from the MQL, solid lubricants also play a vital role for effective machining by enhancing the surface integrity and tool life due to their structure, eco and environmental friendly characteristics.…”

In this study, an attempt is made to examine the machining response parameters in turning of AISI 1040 steel under different lubrication environment. Subsequently, design of experiment technique Response surface methodology (RSM) is used for analyzing machining performance by varying cutting conditions with the use of 2wt% of CNT/MoS2(1:2) HNCF. Regression models are developed for multiple machining responses. Optimization is performed for these models by using desirability function, which converts multi-objective into single objective. Then the optimal setting parameters for single objective is found. Significant reduction in main cutting force (Fz), cutting temperature (T), surface roughness(Ra) and tool flank wear (Vb) are found with the use of 2wt% of CNT/MoS2(1:2) HNCF compared to other lubrication environment. Significant factors that affect the main cutting force (Fz), the temperature in the cutting zone are cutting speed, feed rate and depth of cut. Parameter depth of cut has an insignificant effect on tool flank wear and surface roughness (Ra). The optimal cutting conditions for four multi-objective optimization of main cutting force (Fz), cutting temperature, surface roughness (Ra) and tool flank wear are found to be cutting speed 70.25 m/min, feed 0.13 mm/rev and doc 0.5mm at desirability value of 0.907.
