6 . Maintenance operations & reliability
Equipment inherently degrades with every single operating hour. Relying on a “run-to-failure” maintenance strategy guarantees unpredictable downtime and severe production bottlenecks. Total Productive Maintenance is the necessary shift from reactive repair to proactive reliability.
This chapter defines the mechanics of autonomous maintenance, preventative schedules, and predictive analytics. By educating and empowering operators to actively maintain their own equipment, we maximize Overall Equipment Effectiveness (OEE) and significantly extend the lifespan of our expensive capital assets.
- 6.1 Maintenance governance: KPIs, roles & escalation
Total Productive Maintenance (TPM) is more than a cleaning schedule; it is a systematic approach to maximizing Asset Utilization. In high-volume electronics manufacturing, unplanned machine downtime directly wastes capital. The operational model must...
- 6.2 Preventive maintenance planning
Preventive maintenance is a foundational commitment between Facilities Engineering and Manufacturing Operations. In high-precision electronics assembly, facility systems are active, critical process variables. For example, a drop in dynamic compresse...
- 6.3 Predictive maintenance
Predictive Maintenance (PdM) is fundamentally about buying time. While Preventive Maintenance relies on broad statistical estimates (replacing parts "just in case"), PdM actively monitors the asset for the very early physical signatures of distress—s...
- 6.4 Asset register, criticality & spare parts policy
Managing assets in an ISO 9001/13485 manufacturing environment is more than just an accounting task; it is the technical foundation for ensuring your processes are ready and reliable. Think of it this way: using an uncalibrated torque driver doesn't...
- 6.5 Breakdown response standard: safe isolation, restart verification
A sudden machine breakdown is a high-pressure event where adrenaline can easily override established, logical protocols. This is precisely when preventable accidents occur. The intense pressure to resume production can lead to dangerous shortcuts, su...
- 6.6 Root cause analysis
In a mature Total Productive Maintenance (TPM) environment, simply "fixing" the machine is merely the first, tactical step. The ultimate strategic goal is not just a fast repair; it is ensuring the failure does not happen again. Root Cause Analysis (...
