“…Chavan et al [52] reported that the CS mainly influences tool wear and cutting force during the machining of Nimonic 80A using an alumina-based ceramic insert. It was recommended to go for medium FR and DOC and higher CS for dry machining of Nimonic alloy 80A using an alumina-based ceramic insert.…”

Superalloys have gained prominence in recent years in various sectors, namely, spacecraft, marine, power, defense, vehicular and others, due to their ability to withstand high temperatures of up to 980 °C without deformation. Nimonics are Nickel-based superalloys usually known to be hard-to-machine materials due to their high strength at high temperatures, higher hardness, low thermal conductivity, and tendency to react with tool material. All these factors increase the level of difficulties in the machining of Nimonic superalloys. Numerous studies have examined various facets of machining of Nimonic alloys. This article summarizes the observation from 152 research articles to offer a reasonable engineering overview of the study of Nimonic alloys. An overview of Nimonic superalloys and their applications is given first. Then, various conventional and non-conventional machining processes, problems associated with multiple machining processes and methods to rectify the issues concerning the machining process have been reported. Thus, this summary will certainly help industrialists and academic researchers for further research work in machining Nimonic alloys.

“…In the dry condition, more craters and chipping were found on the surface due to the tool and work interface at higher speeds, whereas in the ASCF condition, fewer craters and chipping were found on the surface due to the presence of solid lubricants during the machining process, resulting in a lower tool wear rate (Danish et al, 2022;Gupta et al, 2022). During the turning of the workpiece in both dry and ASCF conditions, the adhesive chipping layer was visible on the rake surface of the tool (Bhatt et al, 2010;Chavan et al, 2019). When opposed to dry machining, ASCF displays less crater wear and chippings due to the presence of high thermal stress and a high strain hardening rate during the machining process.…”

Manufacturing sectors strive towards low-toxic, environmentally friendly machining to combat climate change. Due to its low heat conductivity, machining Inconel 718 alloy is a difficult process nowadays. The purpose of this research is to investigate the turning of Inconel 718 alloy under PVD TiAlN inserts, in two distinct environments: Dry and Atomized spray cutting fluid (ASCF). The effect of various machining performances such as Surface roughness (Ra) and Tool life (TL) analysis of Inconel 718 alloy on ecologically friendly machining were investigated. According to the results of the study, the surface roughness of the ASCF machining improved significantly, which was around 40%, when compared to its dry machining. The use of the ASCF significantly decreased the notch and abrasion wear of the tool. This was due to its various features, such as its ability to provide effective lubrication and reduce the cutting temperature.

“…Also, the use of spray coolants helps in preventing the formation of abrasion and another diffusion during dry machining. Solid lubricant helps to minimize the amount of heat absorbed by the tool and significantly improve the tool life, as shown in figure 6 [43][44][45][46].…”

Atomized spray cutting fluid (ASCF) is a sophisticated machining technique that achieves higher productivity, enhanced surface quality, extended tool life, and cost benefits.This research aims to analyze the influence of cutting process parameters on Inconel 718 alloy turning in dry and ASCF cutting environments. The critical machining indices such as surface roughness, machining cost, power consumption, and tool life were analyzed concerning these two cooling environments. The cutting parameters were optimized using desirability functional analysis and two types of multicriteria decision making (MCDM) method, such as additive ratio assessment method (ARAS) and combinative distance-based assessment (CODAS) method, were investigated. The composite desirability index (CD) of optimum parameter setting(A2B1C2D2) is improved by 6.34 % compared to the initial parameter setting (A2B1C2D1). The optimum parameters from the MCDM technique are obtained as a cutting speed of 200 m/min, feed rate of 0.08 mm/rev, and depth of cut of 0.2 mm under ASCF environment. ASCF machining significantly minimize the surface roughness, machining cost and power consumption , maximize the tool life by about 16% , 51%, 17% and 48% respectively as compared with dry machining
