Int. J. Extrem. Manuf.

Material removal in the cutting process is regarded as a friction system with multiple input and output variables. The complexity of cutting friction system is caused by the extreme conditions existing on the tool-chip and tool-workpiece interfaces. The key issue is extremely important to use knowledge of cutting friction behaviors to guide researchers and industrial manufacturing engineers in designing reasonable cutting processes to reduce tool wear and improve surface quality. This review focuses on the state of the art of research on friction behaviors in cutting processes as well as future perspectives. First, the cutting friction phenomena under extreme conditions, such as high temperature, large strain/strain rates, sticking-sliding contact states, and diverse cutting conditions are analyzed. Second, the theoretical models of cutting friction behaviors and the application of simulation technology are discussed. Third, the factors that affect friction behaviors are analyzed including material matching, cutting parameters, lubrication/cooling conditions, micro/nano surface textures and tool coatings. Then, the consequences of the cutting friction phenomena including tool wear patterns, tool life, chip formation, and the machined surface are analyzed. Finally, the research limitations and future work for cutting friction behaviors are discussed. This review contributes to the understanding of cutting friction behaviors and the development of high-quality cutting technology.

“…The wear of flank face is commonly used to assess the failure modes of carbide cutters and can be classified as adhesive wear, diffusion wear, abrasive wear, and oxidation wear [30][31][32].…”

“…Figure 14 shows the morphology of flank face of WC-Ni-Zr after cutting test. The wear modes of WC-Ni-Zr cutters also include mainly adhesive wear, which is the main wear mode of cemented carbide cutters at low and medium cutting speeds [30]. The spalling of coating also occurs and is more severe than that for WC-Co-Zr cutters.…”

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.

“…Zhang et al [6] research shows that improving the integrity of the machined surface can improve its corrosion resistance. Chang et al [7] concluded that the wear rate and friction coefficient are related to the machined surface, if the workpiece has a good machined surface, the smaller these two parameters will be. Consequently, the surface integrity directly link with economic profile [8,9] .…”

With the increasing environmental requirements in machining techniques, cryogenic machining technology gains more and more attention recently. We have carried out cryogenic cutting tests on 6061 aluminum alloy in this study. The effects of cryogenic cooling on machined surface roughness, surface hardness and surface functional properties were studied. The experiment results show that cryogenic cutting can reduce the surface roughness, improve the surface hardness, and thus the machined surface can obtain better wear resistance and corrosion resistance.
