Coding for defect detection in glass fibre production

Detecting defects during glass fibre production is a critical task that impacts efficiency, costs and sustainability. During a recent COGNIMAN coding day in Kristiansand, Norway, engineers and technical experts from 3B-Fibreglass, IBM, SINTEF, NORCE and Montimage worked together to advance the sensor solutions using artificial intelligence (AI).

Tackling defects in glass fibre production

In glass fibre manufacturing, even small defects like fibre breaks can cause delays, waste and higher costs. The team focused on developing an AI system to detect defects early, reducing the risk of production interruptions. The challenge was to create an accurate detection system that minimises false alarms, which can lead to unnecessary disruptions.

Using AI and data to improve detection

The team used data provided by 3B-Fibreglass to train AI algorithms to identify defects with high precision. This work involved improving the system to handle variability in production conditions, such as temperature changes and fibre thickness, which can affect defect formation.

By refining the algorithms, the team aims to reduce waste and improve the quality of glass fibre products. Early detection ensures that defects don’t disrupt the production line or compromise product standards.

Streamlining collaboration with Microsoft Azure

The team used Microsoft Azure DevOps, a cloud-based platform for project management and collaboration. This tool helped track tasks, share updates and manage progress efficiently.

Microsoft Azure is like a toolkit for teams working on complex projects. It includes services for:

• Coding and testing: Writing and testing software
• Data analysis: Understanding large datasets, like those used in defect detection
• Project management: Keeping tasks organised and on schedule

Practical goals for glass fibre production

The project focuses on improving defect detection at the bushing level, where fibre breaks often occur. Better detection can lead to:

• More effective sensor systems.
• Reduced cleaning and maintenance needs.
• Shorter repair times and fewer production interruptions.

These improvements would increase efficiency, reduce waste and lower production costs.

What’s next?

The session in Kristiansand was a step toward creating a reliable defect detection system for glass fibre production. The next phases will focus on further refining the AI algorithms and testing them.
