Machine downtime is a widespread problem in the industrial world — 82% of organizations have reported experiencing at least one unplanned outage each year and 45% of which were unable to provide products or services to customers as a result.
If machine downtime is such a drawback on revenue and productivity, why is it still so prevalent? The issue lies in traditional means of machine maintenance. Facilities have relied primarily on two methods in the past. The first is reactive maintenance: When workers notice symptoms of machine problems (such as poor quality outputs or machines breaking altogether), they reactively investigate the issue. This model is problematic because once workers know that a problem exists, the machines have already failed and product/output has already been affected. Downtime to repair failed or underperforming machines means stalled or halted production lines, reduced revenue, and an overall hit to productivity.
The second traditional maintenance method takes a more proactive approach, but still fails to significantly reduce machine downtime. Preventive maintenance aims to catch problems sooner as workers perform maintenance tasks on a time-based schedule. However, most machine failures are difficult to predict using solely operating hours or life cycles as a determining factor of when they need maintenance. This approach can also mean longer periods of downtime. If a machine begins underperforming shortly after its scheduled maintenance, it’s likely to continue underperforming — and perhaps even fail — before its next scheduled check.
Machine Health Is the Key to Reducing Machine Downtime
What’s more, both of the above maintenance methods have been traditionally focused on responding to symptoms of machine underperformance or failure rather than detecting potential issues before they arise. In recent years, however, the industrial world has seen an increase in a third type of maintenance focused more on catching problems ahead of time: predictive maintenance. Predictive models use many different methods (including vibration, oil analysis, thermography, and ultrasound data) to predict and prevent failures by early indicators of machine malfunctions.
Predictive maintenance gets us one step closer to solving the downtime problem, but most facilities are still missing one link that can make the biggest difference: an approach emphasizing machine health. Route based predictive maintenance tools can alert workers of a problem at an early stage, but without continuous monitoring, workers must still come around to check the machines periodically to notice that something has gone amiss. And even if you have sensors mounted on a machine, if they aren’t advanced enough, they may not automatically diagnose the issue and won’t provide maintenance teams the root of the issue, or suggest ways to fix it — so in the end, they’re more like a check engine light.
Machine health, on the other hand, is a framework that elevates predictive maintenance with continuous machine health monitoring. Powered by the IoT and artificial intelligence, this framework can alert workers at the exact moment when issues are detected — providing facility teams prescriptive diagnostics of what’s been detected, and how to fix it. To get a sense of how machine health could fit into your operation, consider how it addresses the following core causes of machine downtime to keep factories firing on all cylinders:
Unplanned downtime in manufacturing is an inevitable phenomenon, but even planned downtime can hinder your productivity. Nothing can stop these issues altogether, but taking steps to reduce downtime now can have a big impact on your revenue and productivity in the future. Stop solving problems after they’ve already happened, and start taking a real-time approach to keeping your machines healthy.
