“…Research has also shown that the flow direction of the chip is related to the shape and size of the texture on the rake face of the tool. Coroni et al [27] used Deform 2D to predict the optimal experimental conditions for orthogonal machining of various titanium alloys, and the simulation results agree well with the experimental results. Mishra et al [28] used AdvantEdge FE simulation software to study the effects of different texture shapes (circles, squares, triangles, and ellipses) on the cutting force of titanium alloys during processing under dry conditions, as well as different texture areas, densities, and the effect of depth on changes in the cutting force.…”

The hard turning process has been widely used in the field of hard material precision machining because of its high efficiency, low processing residual stress, and low environmental pollution. Due to its undesirably processing quality, it is still not a substitute for traditional grinding, so many studies have reported that the process has been optimized. However, there has been little research on the geometry optimization of hard cutting tools, which have a great influence on the traditional machining process. In this paper, two tools with different rake face shapes are designed. The finite element analysis method is used to compare their performance with a conventional plane tool while turning hardened steel. The results show that the cutting performance of the designed tool T1 and T2 (chip morphology, cutting force, and cutting temperature) and the quality of the machined surface are improved compared with the tool. The cutting force decreased by 12.72% and 14.74%, the cutting temperature decreased by 7.56% and 9.01%, respectively, and the surface residual stress decreased by 26.56% and 28.66%.

“…Predicted results from the simulation were in good agreement with the experimental results. [2]. Numerical simulation on Ti-6Al-4V titanium alloy was carried out to understand the adiabatic shear band and chip formation phenomena using three different material models such as Johnson-cook (J-C), Hyperbolic TANgent (TANH) and…”

“…14,000 elements were used to define the cutting tools and the tool tip was re-meshed with 1,00,000 elements for obtaining better distribution of output parameters such as temperature and friction co-efficient. Thermal boundary conditions were defined as given in equation (2) to allow the heat transfer and heat conduction from work piece to the cutting tool at high contact pressure. [20].…”

“…The development of hardware and software has led to improvements in numerical methods such as FEM, Finite Volume Method (FVM), Boundary Element Method (BEM), among others, as highlighted by Maliska [11]. Numerical methods are applied not only to study the temperature field in tools but also to estimate the cutting force in machining, as was the case in the work of Coroni and Croitoru [12], in which the authors applied the Difference Finite Method for obtain the cutting force in an orthogonal model. Another application of numerical methods was to study the contact resistance between solid domains, as was done in Goodarzi et al [13] and Zheng et al [14] to improve contact resistance prediction.…”

In machining processes, cutting tools reach temperatures higher than 900ºC, thus deteriorating their mechanical properties. To reduce this problem, cutting tools are coated with materials possessing thermal insulation characteristics. Such coatings benefit machining, providing faster cutting speeds and tools life. However, the heating of the tools is still present. Therefore, this work simulates the transient heating phenomenon of a tool and its tool holder, considering the presence of the coating. The effects of convection, radiation, and contact resistance between the tool and the tool holder are also considered. The thermophysical properties of the tool elements depend on temperature. Experimental measurements of parameters related to contact resistance were carried out to make the thermal model closer to real situations. The COMSOL program was used to solve the heat diffusion equation using the Finite Element Method. Comparisons of calculated temperatures are presented for the uncoated (substrate only) and coated inserts with aluminum oxide (Al2O3) and titanium nitride (TiN), respectively. Finally, the results and the consequences of the assembly parameters in the fields of temperature and contact resistance are discussed.
