Maintenance Awareness Flashcards

Which type of maintenance is performed based on equipment condition monitoring rather than a fixed schedule?

Answer: Predictive maintenance

Predictive maintenance uses condition monitoring data (vibration, temperature, oil analysis) to trigger service only when indicators show degradation.

What does the acronym OEE stand for in a manufacturing maintenance context?

Answer: Overall Equipment Effectiveness

OEE (Overall Equipment Effectiveness) measures availability, performance, and quality to gauge how effectively equipment is being used.

A machine guard is removed during maintenance. When must it be reinstalled?

Answer: Before the machine is returned to service

Guards must be reinstalled and verified before a machine is returned to production to protect operators from hazards.

What is the primary purpose of a lubrication schedule in a maintenance program?

Answer: To prevent premature wear and extend equipment life

Regular lubrication reduces friction and heat, preventing premature wear and extending the service life of mechanical components.

When a production technician notices an unusual smell near electrical equipment, the FIRST action should be to:

Answer: Immediately report it to maintenance or supervision

Unusual smells near electrical equipment can signal overheating or arcing; reporting immediately allows qualified personnel to investigate safely.

What does MTBF measure in a reliability-centered maintenance program?

Answer: Mean Time Between Failures

MTBF (Mean Time Between Failures) measures the average operating time between one failure and the next, indicating equipment reliability.

Which condition would most likely be identified during a vibration analysis of a rotating shaft?

Answer: Bearing wear or imbalance

Vibration analysis detects issues such as bearing wear, shaft imbalance, misalignment, and looseness in rotating machinery.
