Predicting factory equipment failures before downtime

Unplanned downtime from aging motors and conveyors halts production lines with little warning.

Problem

Maintenance follows calendar schedules or run-to-fail; vibration and current signals are underused.

Technicians react to alarms and operator reports; spare parts may not be on hand.

Lost throughput and rush logistics for parts.

Sensor models can estimate remaining useful life and schedule maintenance windows.

Sensor coverage cost; rare failure labels.

Unnecessary interventions; ignoring novel failure modes.

Time-based PM and OEM service contracts.

Time-based replaces healthy parts; contracts still miss intermittent faults.

NIST smart manufacturing maintenance research
Supports predictive maintenance with measurement science caveats.
