The article aims to model and analyze the thermal behaviour of coated cutting tools in dry machining.
Developed a transient thermal model using finite element method.
Applied the model to uncoated, TiN-coated, and TiN/Al₂O₃ double-coated tool configurations.
Conducted experimental dry turning tests to validate numerical predictions.
Numerical model accurately predicted temperature changes at the tool–chip interface.
Uncoated tools showed rapid heat penetration and large internal thermal gradients.
TiN coating raised surface temperature but minimally impacted heat diffusion.
TiN/Al₂O₃ multilayer significantly reduced heat transfer, leading to lower internal temperatures.
