5.0 WHAT IS PREDICTIVE MAINTENANCE?
Predictive Maintenance can be defined as collecting information from
machines as they operate to aid in making decisions about their health,
repair, and possible improvements in order to estimate when maintenance
should be performed before any unplanned breakdown. Machinery
maintenance has evolved because of the demands to become more
profitable through reduced maintenance costs. Below is the progression
of these maintenance philosophies:
• Break Down Maintenance
•
Preventive Maintenance

Predictive Maintenance
Break Down Maintenance
occurs when repair action is not taken on a
problem until the problem results in the machine’s failure. Run to failure
problems often cause costly secondary damage along with expenses
resulting from unplanned downtime and unplanned maintenance.
