The present paper shows the work done around the correction of laser milled geometries on cutting tools made of tungsten carbide material. After the exposition of the error detection and correction methodology to be followed after the machining of a geometrical feature, the experimental procedure for the application of the methodology is exposed. Finally, the obtained results are exposed and discussed. The results show that the error detection methodology is able to identify properly the defective zones and define a laser milling process for their correction in order to obtain a geometry within the defined tolerances in comparison to the theoretical one.
