“…They reported that feed and laser power mainly affected surface integrity compared to others. You et al studied the resistance to wear of various CVD coatings of cermet substrate and the turning performance of alloy steel grade 4340 [35]. They reported that the TiCN/Al2O3 coating provided the best overall performance over others.…”

Cryogenic treatment has been shown to significantly improve the cutting performance of inserts. Alloy steel grade 4340, renowned for its high impact and abrasion resistance, has extensive application in aircraft landing and high-power transmission gears. In this study, a comparative characterization (microhardness and XRD profile) and dry turning performance evaluation (turned surface roughness and insert wear) of alloy steel grade 4340 were performed using as-received and cryogenically treated coated cermet cutting inserts. The turning operation was carried out with various cutting velocities ( 55, 90, and 150 m/min) and a constant feed and cutting depth (0.111 mm/rev and 1 mm) under dry cutting conditions. The cryogenically treated insert obtained A reduced Ra value compared to untreated conditions at all cutting speeds. In addition, Ra value was reduced to a maximum of 29%. A lower level of insert wear and chip particle deposition at the cutting point was observed with cryo-treated inserts. Finally, it was revealed that the better machining characteristics in terms of reduced Ra values and insert wear with cryo-treated conditions were due to the enhanced wear resistance over the untreated conditions.

“…Through the simulation of the coating temperature by this model, it is shown that the coating with low thermal conductivity can play the role of heat insulation, and it is found that among the studied coatings, TiAlN coating and TiAlN/α-Al 2 O 3 coating are the best thermal insulation coating. By simulating the cutting process, You et al 16 analyzed the influence of the tool coating/matrix system on the cutting temperature, and found that the difference of the intermediate coating between the coating and the matrix would affect the thermal conductivity of the whole system, thus affecting the temperature distribution in the heat transfer process. It is also found that the surface morphology of the coating affects the temperature distribution of the chip-tool interface.…”

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.
