“…The thin layers, and high number of interfaces between layers (similar principle to the multilayered coatings), confers high strength to the coating. Increasing the resistance of the coating against crack propagation, as mentioned in Section 3 [48]. The nanolayers thickness also influences the coating resistance.…”

The milling process is one of the most used processes in the manufacturing industry. Milling, as a process, as evolved, with new machines and methods being employed, in order to obtain the best results consistently. Milling tools have also seen quite an evolution, from the uncoated high-speed steel tool, to the now vastly used, coated tools. Information on the use of these coated tools in recent scientific researches was collected. The coatings that are currently being researched are going to be presented, highlighting some novel advances in the nanocomposite and diamond coatings area, as these coatings are seeing a growing use in the industry, with very satisfactory results, with performance and tool-life increase. Wear mechanism of various types of coatings are also a popular topic on recent research, as the cutting behavior of these coated tools provides valuable information on the tool’s-life. Furthermore, analysis of these mechanisms enables for the selection of the best coating type for the correct application. Recently, the employment of coated tools paired with sustainable lubrication methods as seen some use. As this presents the opportunity to enhance the coated tool’s and the process’s performance, obtaining better results, in terms of better tool-life and better surface finish quality, in a more sustainable fashion.

Existing research on coated tools does not predict data while exploring the changing rules. As well as the traditional cutting process parameters neither guarantees the surface quality of the 30CrMnSiNi2A nor attains high material removal rate (MRR). Accurate control and prediction of workpiece three-dimensional surface roughness (Sq) and specific cutting energy consumption (SCEC) are of vital significance to improve quality, reduce cost and improve efficiency. Here, according to the new SCEC calculation model and the influence of measuring position on Sq, the SCEC and Sq values are accurately obtained. Then, based on the idea of fitting formula, the influence of cutting parameters on SCEC and Sq in high-speed dry (HSD) milling of 30CrMnSiNi2A steel is analyzed according to CVD and PVD coated inserts. Finally, the SCEC and Sq prediction models considering coating type, cutting speed, feed per tooth and cutting width are established by using the XGBoost algorithm. The R2 values of SCEC and Sq are 0.92465 and 0.91527, respectively, indicating that the model has a good prediction effect on experimental data. The feasibility of HSD milling of 30CrMnSiNi2A steel with CVD and PVD coated inserts is verified by analyzing SCEC, Sq and cutting temperature, which provides experimental basis for high efficiency and high precision machining of 30CrMnSiNi2A steel.

“…With the rapid development of the modern manufacturing industry, more crucial requirements, such as simultaneously high wear resistance and high toughness, are being put forward on the performance of cemented carbides [8,9]. In order to obtain better properties, current development on cemented carbides is mainly focused on functionally graded carbides (FGCs) and cemented carbide coatings [10][11][12][13][14]. The FGCs shows gradient microstructures from surface to internal portion, which provides both higher wear resistance (surface) and toughness (internal portion) and hence better overall performance than conventional carbide with homogeneous microstructure [15][16][17][18][19].…”

Currently, the research on mechanical behavior and cutting performance of functionally graded carbides is quite limited, which limits the rapid development of high-performance cemented carbide cutting tools. Based on WC-Co-Zr and WC-Ni-Zr, this study synthesized two kinds of cemented carbide cutters, i.e., the cemented carbide cutters with homogeneous microstructure and functionally graded carbide (FGC) cutters with FCC phase ZrN-enriched surfaces. Furthermore, TiAlN coating has been investigated on these carbide cutters. Mechanical behavior, friction, wear performance, and cutting behavior have been investigated for these coated carbides and their corresponding substrates. It was found that, as compared with coated cutters on WC-Co/Ni-Zr carbide substrates with homogeneous microstructures, the coated cutters on WC-Co/Ni-Zr FGC substrates with FCC phase-enriched surfaces show higher wear resistance and cutting life, and the wear mechanism during cutting is mainly adhesion wear.
