“…Considering that TW significantly and directly affects F c , a local model formulation, as proposed with the tool geometry evolution, has to be considered to improve the model precision; however, it is challenging to consider VB max > 0.25 mm in a predictive model, as it creates too many random TW profiles. Zheng et al [144] numerically (Figure 12) and experimentally assessed the machinability of INCONEL ® 718 in milling. The FEA model, produced in AdvantEdge ® v7.1 from Third Wave System © , was used to analyse the stress field, T distribution, and F c .…”

Machining INCONEL® presents significant challenges in predicting its behaviour, and a comprehensive experimental assessment of its machinability is costly and unsustainable. Design of Experiments (DOE) can be conducted non-destructively through Finite Element Analysis (FEA). However, it is crucial to ascertain whether numerical and constitutive models can accurately predict INCONEL® machining. Therefore, a comprehensive review of FEA machining strategies is presented to systematically summarise and analyse the advancements in INCONEL® milling, turning, and drilling simulations through FEA from 2013 to 2023. Additionally, non-conventional manufacturing simulations are addressed. This review highlights the most recent modelling digital solutions, prospects, and limitations that researchers have proposed when tackling INCONEL® FEA machining. The genesis of this paper is owed to articles and books from diverse sources. Conducting simulations of INCONEL® machining through FEA can significantly enhance experimental analyses with the proper choice of damage and failure criteria. This approach not only enables a more precise calibration of parameters but also improves temperature (T) prediction during the machining process, accurate Tool Wear (TW) quantity and typology forecasts, and accurate surface quality assessment by evaluating Surface Roughness (SR) and the surface stress state. Additionally, it aids in making informed choices regarding the potential use of tool coatings.

The study was conducted to predict the stable cutting status and build a model to predict the stable diagram in the milling process of SKD11 steel using a solid flat-end mill cutter. The instantaneous dynamic cutting forces and stable cutting conditions were modeled as functions of different parameters including cutting tool parameters, workpiece parameters, cutting force coefficients, dynamics structural parameters of the technological system, cutting parameters, etc. The instantaneous dynamic cutting forces were modeled and verified by experimental process with predicted results to be very close to the measured results, although there are still many differences in the instantaneous values of the cutting forces. A prediction model of stability conditions was also built and verified through the experimental process. With the technology system that was used in this study, the milling process will be stable when machining at a depth of cut less than 0.25mm with all values of spindle speed. Additionally, the stable and unstable points in the predicted stability diagram were verified with ensuring the accuracy. However, at the transition points between stable and unstable zones, it seems that the accuracy of model is lower. The studies to verify and improve the model to predict the stable condition with different cutter -workpiece material pairs using different technology systems are the next direction of this study.

“…Vanadium is another element with great potential to contribute to this type of coating; however, in the literature, studies are focused on characterizing the physical and chemical properties of this coating, causing it to have a gap in terms of its performance and wear resistance in milling operations. Added to this is the fact that there is a gap in the literature on milling of INCONEL ® 718 aimed at finishing operations, wear behavior, and the performance of the process, with the majority concentrated on the turning process [59].…”

The use of coatings on cutting tools offers several advantages from the point of view of wear resistance. A recent technique with great coating deposition potential is PVD HiPIMS. TiAlN-based coatings have good resistance to oxidation due to the oxide layer that is formed on their surface. However, by adding doping elements such as Vanadium, it is expected that the wear resistance will be improved, as well as its adhesion to the substrate surface. INCONEL® 718 is a nickel superalloy with superior mechanical properties, which makes it a difficult-to-machine material. Milling, due to its flexibility, is the most suitable technique for machining this alloy. Based on this, in this work, the influence of milling parameters, such as cutting speed (Vc), feed per tooth (fz), and cutting length (Lcut), on the surface integrity and wear resistance of TiAlVN-coated tools in the milling of INCONEL® 718 was evaluated. The cutting length has a great influence on the process, with the main wear mechanisms being material adhesion, abrasion, and coating delamination. Furthermore, it was noted that delamination occurred due to low adhesion of the film to the substrate, as well as low resistance to crack propagation. It was also observed that using a higher cutting speed resulted in increased wear. Moreover, in general, by increasing the milling parameters, machined surface roughness also increased.
