CWRU — bearing fault classification from the envelope spectrum (reasoning track)
Part of the AI4Manufacturing FORGE corpus (Category C, task T-C1). Each record is the envelope spectrum of a 1 s rolling-element-bearing vibration window with the fault frequencies marked — the representation that supports faithful compute-then-check chain-of-thought. reasoning is empty here; the CWRU-annotated sibling fills it.
Records: 981 (splits {'train': 721, 'test': 260}); labels {'inner_race': 218, 'ball': 215, 'outer_race': 513, 'normal': 35}; evidence_tier {'confirmed': 639, 'weak': 217, 'absent': 125}.
Schema (7-field unified record)

image |
the rendered signal image (bytes embedded) |
annot |
gold fault class: normal / inner_race / outer_race / ball |
reasoning |
chain-of-thought (empty here; filled in the -annotated sibling) |
cate / task |
C / T-C1 (signal fault classification) |

Splits
train / test, bearing-wise (leakage-safe).
Provenance & reproducibility
Generated deterministically by forge_agent/examples/cwru/convert.py (c38f68fad7) → forge_model/CWRU/convert_cwru.py (ccc0f61ce3); see provenance.json for the full record.
Cleaning (all encoded in the pinned code): excluded the NTN 0.028″ files 3001–3008 (wrong bearing geometry) and the corrupt 191; flagged Smith & Randall (2015) non-diagnosable (sr_nondiagnosable) and acquisition-anomaly files; bearing-wise leakage-safe split (all loads + both sample rates of a physical bearing stay on one side). A computed evidence_tier (confirmed/weak/absent) cross-checks against the Smith & Randall expert grades.
Caveats
- Ball is the hard class — Smith & Randall (2015) grade most CWRU ball faults non-diagnosable (intermittent load-zone contact + smeared BSF); those records carry the correct label but a low
evidence_tier. This is a property of the data, not the converter. - Eval: use the provided bearing-wise split; the within-condition (per-load) split inflates accuracy.
