Manufacturing anomalies introduced during machining of critical parts, although rare in occurrence, have become a significant cause of gas turbine disk cracking events in the aero‐engine. One kind of these anomalies is inclusion of foreign material. Breakage of the machine tool cutting edge can lead to residual tool particles being impacted in the surface of the component. These particles may initiate fatigue crack growth significantly reducing fatigue life. The paper presents electromagnetic methods for their detection and characterization based on eddy currents and residual magnetic fields.
