“…It was obvious that the tools' lives did not advance along with their mechanical properties. A lot of heat would be generated at the tip during the cutting operation, and if the heat cannot be transferred via the tool, the tool's wear resistance will be significantly decreased 25–27 . Therefore, thermal conductivity was another factor in addition to the mechanical properties that affect cutting life.…”

“…A lot of heat would be generated at the tip during the cutting operation, and if the heat cannot be transferred via the tool, the tool's wear resistance will be significantly decreased. [25][26][27] Therefore, thermal conductivity was another factor in addition to the mechanical properties that affect cutting life. The thermal conductivities of the T5, T10, and T15 samples were 16.25, 14.87, and 13.77 W⋅m −1 ⋅K −1 , respectively (as shown in Table 2), which decreased with increasing content of high-entropy carbides and may be the reason why high content of high-entropy carbides was not conducive to improving cutting life.…”

In this study, we investigated the cutting performance and wear mechanisms of Ti(C,N)‐based cutting tools containing varying weight percentages (0%, 5%, 10%, and 15%) of high‐entropy carbide (HEC) (V0.2Nb0.2 Mo0.2Ta0.2W0.2)C phase, when used for turning nodular cast iron. According to the turning test results, the cermet cutting tools containing 0 wt%, 5 wt%, 10 wt%, and 15 wt% HEC phases demonstrated effective cutting lives of 402, 720, 632, and 465 s, respectively. The tool with 5 wt% HEC phase showed the best cutting performance. When cutting nodular cast iron with cermet cutting tools, the main wear mechanisms observed were diffusion, oxidation, adhesion, and abrasion on the flank surface, along with diffusion, oxidation, and abrasion on the rake surface. The results of this study indicated that (V0.2Nb0.2Mo0.2Ta0.2W0.2)C could be adopted as an effective reinforced phase in the cermet cutting tools.

“…Tool coating will also have an important impact on the cutting temperature, which is analyzed by researchers through cutting experiments and finite element simulation. Tu et al 13 simulated the temperature distribution of cBN/diamond coating and TiAlN coating on Si 3 N 4 tool under different parameters by the finite element method, which is verified by the turning test. It is found that cBN coated tools produce less heat than TiAlN coated tools, and the heat dissipation performance of cBN/diamond coating is better than TiAlN coating.…”

Coated tools are currently widely used tool technology in machining. The influence of tool coating on heat transfer has become an active field of research enjoying constantly increasing attention in the field of machining. This paper is devoted to the cutting temperature in machining H13 hardened steel with monolayer coated tools (TiN, TiAlN, and Al2O3) and multilayer coated tools (TiN/TiC/TiN and TiAlN/TiN). Equivalent composite thermal conductivity and thermal diffusivity of multilayer coated tools were calculated using the equivalent approach. The established heat transfer analytical models estimated coating temperature in turning. The effect of tool coating in steady and transient heat transfer was studied, as well as the cutting temperature distribution. It reveals that the tool coating material and coating thickness can influence the cutting temperature distribution of coated tool. Thermal conductivity of coating material affects the steady cutting temperature distribution, and thermal diffusivity of coating material affects the transient cutting temperature distribution of coating tools.

“…The results showed that feed rate is very effected parameter on cutting temperature whereas depth of cut is most effaced parameter on cutting force. Tu et al [15] used finite element method to predict the temperature profile in cutting process. They used cubic boron nitride (CBN) and silicon nitride (Si3N4) and compared with titanium nitride (TiAlN) coatings.…”

This study presents numerical solution by using coupling model between computational fluid dynamic (CFD), and finite element method (FEM) to predicted the temperature distribution through cutting tool. In this study ANSYS/Explicit dynamic used to solve finite element equations in cutting zone. Machining simulations were conducted using Aluminum (AL) and High speed steel (HSS) as a workpeice and tool material respectively. Depth of cut varied from 1.5 mm to 2.5 mm and a cutting speed varied from 6m/s to 10m/s have been considered in the simulations. The CFD model solve by using ANSYS/fluent to find the temperature distribution at the tool surface by using finite volume method. The simulation explained the influence of depth of cut, and cutting speed on cutting temperature. For all simulations, the rake angle is fixed (6°). The rise or reduction in temperature as a result of the various cutting parameters was also estimated and discussed. After solving the problem, it was discovered that the temperature at the tip (tool-work piece contact area) was the highest and gradually decreased towards the surface, and that the results showed a major influence of cutting speed on the temperature generated in the machined models and a very small influence of depth of cut on the workpiece temperature.
