Tracking the “signature” of a machine (the characteristic features of the machine extracted from the vibration signal, usually from accelerometers) evolving over time, it is possible to identify the main causes of vibration and preventively recognize damage and wear of the components, thus performing an accurate diagnosis.

Two steps are fundamental:

• Signal processing is exploited to highlight and extract damage-characteristic features.

• Machine learning is employed to automatically infer anomalies in the vibration response from the extracted features. Such anomaly or novelty, in fact, can be put in relation to damage when confounding influences (i.e. different operational or environmental conditions) can be excluded or compensated.

The aim is to create a reliable diagnostic system to be integrated into machine maintenance regimes so as to foster safety while, at the same time, saving on costs
