Visualising information trends and data analytics for production systems

Unplanned maintenance activities are one of the biggest cost drivers within manufacturing. Late maintenance can cause damage to the products or production components, or even downtime. To prevent this, manufacturers are developing strategies for timely replacement of components or maintenance operations of (crucial) parts in their manufacturing environment.

One of the ways to prevent unplanned maintenance activities is to utilise machine sensor data for continuously monitoring the machine status and health. By timely failure anticipation, downtime can be reduced, and maintenance activities can be optimised and scheduled at a convenient time. However, some critical components require external sensors to monitor their health status for maintenance activities. This is the core of the VITALS project, which is an acronym for Visualisation of Information Trends and AnaLytics of data for production Systems. This is conducted by utilising external sensors and advanced analytics tools for decision-making, as a standalone monitoring system. This AMP-subsided project serves as an initial step towards predictive maintenance for the involved companies.

The VITALS consortium consists of Watson Marlow Bredel from Delden, CM Data from Oldenzaal, and High Tech Maintenance from Hengelo, under the support of the FIP-AM@UT. Watson Marlow Bredel’s core activity is manufacturing hose pumps for thick liquids, such as concrete and oil. These products are mainly applied in the mining and construction industry and food production. The production of the housing of these pump systems involves rotary machining operations with higher cutting forces. Rolling element-bearing, housed in a rotary machining table, plays a crucial role in handling such greater forces that require smart maintenance practices to avoid critical failure. CM Data, specialised in sensor technology and IoT platforms, plays an active role in sensor integration and data acquisition from the production component. High Tech Maintenance is an organisation that specialises in maintenance operations in the heavy-duty industry.

The project aims to successfully link sensor data to failure modes and failure mechanisms, to monitor the rolling element-bearing health status. Using data analytics techniques, amongst other things, a machine learning algorithm will be developed to detect the healthy and failure modes. The final objective is to build a demonstrator that showcases the successful extraction of sensor data from a production machine, to implement a machine learning algorithm to monitor the status and events of the machine and visualise this process on a dashboard. This can lead to extended research toward accurate prediction of a Remaining Useful Life (RUL). Eventually, this method will be extended to other engineering systems.

APPROACH

Central to the VITALS project is integrating sensors on production machines, starting with one Unisign machine. This ensures continuous data collection from critical components, focusing on elements like the rolling element-bearing in rotary machining operations. The collected data is stored to create a comprehensive repository for detailed analysis. Advanced analytics algorithms are then developed to extract insights, identify patterns, detect anomalies, and monitor trends in machine health.

A key component is developing a machine learning algorithm to distinguish between healthy and failure modes. This algorithm is crucial for predictive maintenance by anticipating potential failures. The project culminates in developing a demonstrator that showcases successful integration and analysis of sensor data. This includes implementing the algorithm and visualising results on a dashboard for real-time monitoring. By linking sensor data to specific failure modes, the VITALS project aims to enhance predictive maintenance capabilities, potentially allowing accurate predictions of the Remaining Useful Life (RUL) of machine components and extending these methods to other systems.

OUTCOME

The VITALS project resulted in valuable insights in component health for a predictive maintenance approach in rotating bearings. The project achieved the following results through four main work packages:

• Insight into machine component health status based on real-time signal visualisation
• Collected data through multiple retrofitted sensor measurements
• Created a user-friendly dashboard for component health
• Recommendation to machine operators regarding component behaviour to prevent machine downtime

The current proof-of-concept dashboard provides active decision support to allow timely actions for an efficient and effective resource utilization. Given the ease of retrofitting sensor installation, real-time monitoring can be carried out without interruption production. The outcomes offer an opportunity for strategic decision making and a sustainable use of resources.

This project was made possible through the Regio Deal supported by the Province of Overijssel and the Dutch State.
