This research aims to analyze the thermal effects of titanium nitride coatings on carbide cutting tools.
Compared thermal properties of TiN-coated and uncoated carbide tools during orthogonal machining.
Estimated heat flux and tool-chip interface temperatures using inverse heat conduction methods.
Conducted experiments on gray cast iron to assess thermal influence.
Uncoated tools had significantly higher interface temperatures, averaging an increase of about 300°C compared to coated tools.
Mechanical behavior of the TiN coating primarily contributes to temperature reduction, limiting its thermal barrier effect.
