Preventive and condition-based maintenance
Preventive maintenance acts on a calendar; condition-based maintenance acts on measurement. Combining the two holds equipment availability while concentrating resources where wear is real.
Two complementary logics
The preventive plan handles what wears predictably: lubrication, replacement of wear parts, regulatory checks. It is sized on manufacturer guidance and site history. Condition-based maintenance observes actual state — vibration, temperature, electrical measurement — and triggers intervention when a threshold is crossed. It reserves shutdowns for the machines that need them, and turns an unplanned stop into a scheduled one.
- A preventive plan built on guidance and site history
- Condition measurements taken at regular intervals
- Alert thresholds defined per equipment, revised with experience
- A spare parts store sized on real criticality
- Availability indicators tracked per production line
The three measurements that anticipate failure
Vibration analysis
It reveals a bearing fault, an imbalance or a misalignment long before the ear can hear it.
Thermography
A hot spot on an electrical cabinet signals a loosening connection, therefore a failure ahead.
Electrical measurement
The current a motor draws tells its real load and insulation state, with no production stop.
The maintenance programme, block by block
From mechanics to automation, from diagnosis to organisation, with a block devoted to energy and efficiency. The final workshop produces the complete maintenance plan of a real machine.
| Teaching block | Year | Hours | Credits |
|---|---|---|---|
| Mechanics and power transmission | 1 | 220 h | 22 |
| Electrical engineering and automation | 1 | 220 h | 22 |
| Diagnostics and condition monitoring | 2 | 200 h | 20 |
| Maintenance organisation | 2 | 160 h | 16 |
| Energy and efficiency | 2 | 160 h | 16 |
| Cross-curricular base | 1-2 | 120 h | 12 |
| Workshop and placement | 2 | 120 h | 12 |
Shop-floor questions
Which equipment should I start with?
With the one whose stoppage costs production most: criticality is computed by crossing the impact of a stop with the observed failure frequency. The maintenance organisation block builds that rating on the participant's real equipment fleet.
What place for energy efficiency?
A whole block of 160 taught hours: energy audit, standby generators, photovoltaics, storage and power factor. Maintenance and energy are steered from the same readings.
How do I build a useful spare parts store?
By starting from the most critical equipment and the parts whose lead time exceeds acceptable downtime. That crossing yields a short, quantified list that stands up to the finance department.
