MFCC Crack Features

Dataset of MFCC features extracted from a vibration fault severity dataset for crack faults in a spur gear. The crack fault severity levels were also created in gear Z1. P8 and P9 correspond to cracks created with an angle of 45$^\circ$. The remaining faults have a crack angle of 0$^\circ$. The percent of the crack represents the relative volume of each crack to the volume of the largest crack, P9. In all cases, the crack is located in one tooth. The feature dataset is described in the paper: 'Multi‑level Gearbox Fault Severity Diagnosis Using MFCC, Empirical and Variational Mode Decomposition with LSTM"
