Corrective maintenance

Some examples of using predictive maintenance and predictive maintenance sensors include vibration analysis, oil analysis, thermal imaging, and equipment observation.

To recap, the steps to starting a predictive maintenance program at your facility are:

1. Start small.
2. Identify PdM ready assets.
3. Identify resources required.
4. Implement asset monitoring and begin data collection.
5. Create algorithms to predict failures.
6. Apply to pilot asset.

Five types of maintenance are in fact recurrent in the industry: corrective, preventive, condition-based, predictive and predetermined.

Predictive maintenance simply refers to the fact that service shutdowns come neither too late (when a breakdown occurs) nor too soon (the machine is all right and there is no reason for a shutdown) but at the right moment (when the risk of a breakdown exceeds the accepted threshold).

Predictive maintenance allows manufacturers to lower maintenance costs, extend equipment life, reduce downtime and improve production quality by addressing problems before they cause equipment failures. More high-quality data we can feed into the predictive model the better its accuracy.

Definition. Condition-based maintenance (CBM) is a maintenance strategy that monitors the actual condition of an asset to decide what maintenance needs to be done. Condition-based maintenance can be applied to mission critical and non-mission critical assets.

How to Implement Total Productive Maintenance (TPM)

1. Step 1: Identify a Pilot Area.
2. Step 2: Restore Equipment to Prime Operating Condition.
3. Step 3: Measure OEE.
4. Step 4: Address/Reduce Major Losses.
5. Step 5: Implement Planned Maintenance.

What are the 8 Pillars of Total Productive Maintenance?

• Focused Improvement.
• Autonomy.
• Quality Maintenance.
• Planned Maintenance.
• Early Equipment Maintenance.
• Training and Education.
• Safety, Health and Environment.
• Office TPM.

Overall equipment effectiveness

So as a benchmark, what is considered a “good” OEE score? An OEE score of 100% is perfect production: manufacturing only good parts, as fast as possible, with no stop time. An OEE score of 85% is considered world class for discrete manufacturers.

Theorder pick accuracy is calculated by determining the number of orders that were picked in full versus the orders that were short picked or short packed.
