Maintenance in the digital world

Published:  25 June, 2019

Richard Chamberlain of Bosch Rexroth discusses, taking a proactive approach to maintenance is key to maximising uptime – something that can be supported by digital solutions in today’s Industry 4.0 landscape.

For manufacturers operating in today’s highly competitive global marketplace, unforeseen downtime presents a significant challenge, often leading to higher costs, missed order deadlines and even reputational issues.

With maintenance-related downtime having long presented challenges for manufacturers, the process of predictive maintenance is becoming a useful tool in reducing the risk of expensive facility downtime. With the arrival of Industry 4.0, the latest technologies are moving this function to a truly anticipatory approach. Utilising the data harnessed through strategically-placed sensors, new digital solutions – which can be easily incorporated on the factory floor – generate reliable predictions and recommendations based on machine health and knowledge. Interpreting real-time data, the digital solutions facilitate the implementation of anticipatory management measures, ultimately reducing downtime.

With that in mind, simply installing the means through which big data can be collected is not enough; digital solutions must be combined with the power of human intelligence.

Just as when looking at the far-reaching possibilities of Industry 4.0 as a whole, a digital movement can’t achieve results on its own. In practice, data harnessed through a network of sensors must be visualised, evaluated and acted upon.

Predictive maintenance in the era of Industry 4.0

As technology evolves to capitalise on the presence of big data and support manufacturers in their efforts to maintain maximum competitiveness, the primary drivers for manufacturers to implement these Industry 4.0 developments remain the same: to reduce costs, elevate levels of quality and increase output.

On the factory floor – where components are fully networked and connected to give greater control and visibility of their performance – that can translate into a health index programme for predictive maintenance. In essence, that allows components to be replaced at the most optimal time, taking into account factors such as asset health, as well as the impact on the broader connected factory, so a smooth and efficient flow of operations is always maintained.

Taking a big picture approach

To maximise the impact of these digital solutions, it is critical for changes to be precisely planned. Here, it is important to remember that digital technologies are highly scalable and can match even the most complex of production environments. Even legacy machinery can be brought in line with the digital future by adapting equipment to accommodate intelligent sensors, controls and drives to form the basis for comprehensive predictive analysis. Once connected to an end-to-end system, the process of predictive maintenance through machine learning is perfectly aided.
