“…The one-dimensional heat conduction model is established from the radium point in tool-chip contact area with the x-coordinate perpendicular to the rake face of cemented carbide tool. As illustrated in researches [17], the heat exchange coefficient h at tool-cutter arbor interface can be assumed as constant 4971 W/(m 2•• C). The heat convection between the tool and environment air (temperature T ∞ = 25 • C) can be neglected compared with the severe heat conduction within tools.…”

“…The model was verified accurate with the interval temperature measured with the embedded thermocouple in dry orthogonal cutting experiment. Zhao et al [17] predicted temperature distribution within cemented carbide tool with one-dimensional heat transfer model by applying constant temperature on tool rake face. The proposed method was verified convenient and valid with the simulating experiment.…”

“…The temperature distribution within tool body is difficult to be obtained due to the complex calculation of moving heat source method [14]- [16]. The generated heat flux cannot be determined with the heat transfer model proposed by Zhao and Liu [17] due to the assumed constant rake face temperature. There is a shortage of method for integrated estimation of the generated heat flux and tool temperature in cutting Inconel 718.…”

Inconel 718 has been taken as the difficult-to-machine material for manufacturing aerial turbine disk due to its superior high-temperature resistance and high hardness. Massive heat flux generated at the tool-chip interface, and high tool temperature can induce severe tool wear in cutting Inconel 718 with cemented carbide tool. Determining the generated heat flux and tool temperature in the cutting process is crucial to illustrate the tool wear mechanism. However, there is a shortage of method for integrated estimation of the heat flux generated at the tool-chip interface and temperature distribution within the tool in cutting Inconel 718. In the current study, the one-dimensional inverse heat conduction model was proposed for the integrated prediction of generated heat flux and tool temperature. First, the heat flux generated at the toolchip interface was inversely calculated with the measured rake face temperature. The heat flux generated at tool-chip interface and heat flux dissipated into tool were increased with cutting speed. Then, the temperature distribution within the cemented carbide tool was determined with the derived analytical solution. Temperature interval between rake face temperature and reverse surface temperature was increased with cutting speed. Finally, the predicted heat flux values were verified accurate with the relative error of less than 3% compared with the research results from the modified Merchant's chip formation model. The proposed model can be used for predicting heat flux and temperature distribution for other tool and workpiece pairs.

“…The TiAlN coating thicknesses affected the coating thermal barrier and antifriction. Zhao and Liu [8] used the established theoretical model of the monolayer TiAlN coated tool to show that an increase of the coating thickness could improve the thermal barrier. Zhao and Liu [9] utilized a two-color thermometer to measure the cutting temperature in the dry turning of Inconel 718 with TiAlN tools (coating thickness of 1 μm and 2 μm).…”

“…In addition to establishing the model, it is also found that the thermal conductivity of the coating has an important effect on the cutting temperature. The lower thermal conductivity of Ti 0.41 Al 0.59 N coating material and cemented carbide will generate the instantaneous thermal barrier effect [23], which can effectively reduce the cutting temperature. Moreover, the TiAlN coating can improve tool life, because of the lubricating ability and anti-adhesion properties [24].…”

The cutting performance of cutting tools in high-speed machining (HSM) is an important factor restricting the machined surface integrity of the workpiece. The HSM of AISI 4340 is carried out by using coated tools with TiN/TiCN/TiAlN multi-coating, TiAlN + TiN coating, TiCN + NbC coating, and AlTiN coating, respectively. The cutting performance evaluation of the coated tools is revealed by the chip morphology, cutting force, cutting temperature, and tool wear. The results show that the serration and shear slip of the chips become more clear with the cutting speed. The lower cutting force and cutting temperature are achieved by the TiN/TiCN/TiAlN multi-coated tool. The flank wear was the dominant wear form in the milling process of AISI 4340. The dominant wear mechanisms of the coated tools include the crater wear, coating chipping, adhesion, abrasion, and diffusion. In general, a TiN/TiCN/TiAlN multi-coated tool is the most suitable tool for high-speed milling of AISI 4340, due to the lower cutting force, the lower cutting temperature, and the high resistance of the element diffusion.
