Monitoring the material properties and microstructure after mechanical processing is a crucial aspect in quality control for manufacturing industry. This study aims to estimate the residual stress occurring after drilling process in metallic specimens. The heat generated during the laser-cut process changes the grain morphology and consequently the heat conductivity in the hole proximity area. The proposed methodology lays in the context of nondestructive techniques and is based on thermography and advanced signal processing methods.
