## 1 Introduction  
The aerospace industry uses nickel-based alloys in its constructions, particularly in aircraft engines [1]. An important property of alloys like Inconel is their ability to be used in temperature ranges from \(-250\)\({}^{\circ}\)C to 700 \({}^{\circ}\)C [2, 3]. Inconel 718 is one of the most commonly used superalloys. According to [4], about 45% of forgings and 25% of castings used in the aerospace industry are made from Inconel 718. At the same time, other properties of this alloy, such as its tendency to strengthen, high strength and hardness at high temperatures, tendency to react with the tool, low thermal conductivity and the presence of chromium, titanium, molybdenum, niobium, and tungsten carbides at grain boundaries, result in very poor machinability of this alloy [5, 6]. The most commonly used materials for cutting tools in the machining of Inconel 718 alloys are coated and uncoated sintered carbides and ceramics. [PERSON] et al. [7] conducted research on the impact of wear-resistant coatings on surface quality and dimensional accuracy. In their studies, they used cutting inserts for turning with the same cutting edge geometry but different CVD and PVD coatings. The cutting length in these tests was 1600 m. The study concluded that the insert with the hardest coating did not characterize the highest wear resistance, and thus did not give the most favorable results for the specified criteria. [PERSON] et al. [8] analyzed the wear mechanisms of cutting inserts with multi-layer TiAl/TiAlN coatings in finish turning processes, both wet and dry. They found that the cutting edge angle significantly affects insert wear. They also confirmed the possibility of using uncoated sintered carbide inserts for dry cutting. [PERSON] et al. [9] also conducted dry machining studies of Inconel 718 using TiN/TiAlN coated inserts and uncoated inserts. The uncoated inserts were tested with coolant, while the coated inserts were tested without coolant. The researchers aimed to demonstrate that using PVD-coated tools in dry machining is a sustainable strategy for achieving eco-friendly machining. [PERSON] et al. [10] conducted comparative studies of turning with sintered carbide inserts with TiAlN/AlCr2O3 coatings, both dry and using atomized spray cutting fluid (ASCF). They found that the use of ASCF resulted in up to 34% lower surface roughness compared to dry machining, as well as a significant reduction in abrasive wear and notch formation on the cutting edge. These effects were explained by the lubrication effect of the spray coolant and the reduced cutting temperature at the tool-chip interface. [PERSON] et al. [11] studied the thermophysical properties of TiAlN coatings applied to sintered carbide inserts. They observed that increasing the Al concentration enhances the crystallinity of the coating, which simultaneously increases its hardness and thermal conductivity. The pinning effect of the coatings increased with higher Al concentrations, which could reduce the friction coefficient. [PERSON] et al. [12] performed dry turning tests using carbide inserts with different edge radii, applying variable cutting speeds and feed rates. They found that surface roughness was more dependent on feed rate and tool radius. Increasing the feed rate resulted in higher surface roughness, while increasing the tool radius led to a reduction in roughness. Simultaneously, work hardening due to deformation increased with higher feed rates and cutting speeds, while a reduction in work hardening was observed when using larger tool radii. The high costs associated with the disposal of used coolants serve as an impetus for researchers to look for alternative cooling/lubrication methods in the machining of Inconel 718 alloys. [PERSON] et al. [13] analyzed the tool wear of cutting tools used for machining Inconel 718 with cryogenic cooling and minimum quantity lubrication (MQL) with nanoparticles compared to dry and wet machining. The results showed that both dry and cooled machining resulted in lower tool wear compared to MQL.
