Overall Equipment Effectiveness (OEE) is a single metric used in manufacturing to measure how well your equipment performs compared to its ideal state. It factors in three key aspects: availability (uptime vs. downtime), performance (production speed compared to maximum speed), and quality (percentage of good parts produced). OEE essentially tells you what percentage of the planned production time is truly productive, offering valuable insights into optimizing your equipment and maximizing its overall effectiveness.
Equipment Health Monitoring (EHM) is not directly included in the calculation of Overall Equipment Effectiveness (OEE), yet it plays a crucial role in improving the three key factors that contribute to OEE:
- Availability: By proactively identifying potential equipment issues through health monitoring, companies can schedule maintenance before breakdowns occur, minimizing unplanned downtime and increasing availability.
- Performance: Monitoring equipment health can help detect performance degradation early on, allowing for adjustments to be made and optimizing production speed to approach the maximum capacity.
- Quality: Early detection of equipment issues through monitoring can also help prevent the production of defective products, contributing to a higher percentage of good parts produced and improving quality.
