CBM (Condition-Based Maintenance)

Definition

CBM (Condition-Based Maintenance) is a maintenance strategy that monitors the actual condition of equipment and performs maintenance only when necessary. Unlike routine periodic inspections or time-based preventive maintenance, it determines the optimal maintenance timing based on real-time equipment condition data.

Application in Manufacturing

Real-time Monitoring

• Continuous data collection through vibration, temperature, and pressure sensors
• AI algorithms automatically detect anomalies compared to normal patterns
• Early detection of failure precursors such as bearing wear and motor overheating

Cost Optimization

• 30-40% reduction in parts replacement costs by eliminating unnecessary preventive maintenance
• Minimized unplanned equipment downtime
• Efficient allocation of maintenance personnel

Key Points

AI-powered CBM utilizes machine learning to predict equipment degradation states. For example, by analyzing hydraulic pressure patterns in injection molding machines, pump replacement timing can be notified 2-3 weeks in advance, enabling spare parts preparation and planned maintenance. This approach reduces false alarms by over 70% compared to simple threshold-based alerts.
