The practice of limiting the stresses on components/subsystems to levels well within their specified or proven capabilities in an effort to improve reliability.
An event when machinery is not available to produce parts at specified conditions when scheduled or is not capable of producing parts or performing scheduled operations to specification. For every failure, an action is required to bring the machinery back to its intended production capability.
Mean Time Between Failures (MTBF)
The average time between failure occurrences. The sum of the operating time of a machine divided by the total number of failures.
The average time to restore machinery to specified conditions.
Proactive Maintenance [Preventive and Predictive]
Preventive maintenance are all actions performed in an attempt to retain a machine in specified condition by providing systematic inspection, detection, and prevention of incipient failures.
Predictive maintenance are techniques used to detect potential failures so that action can be taken to avoid the consequences which could occur if they degenerate into functional failures.
