Design Principles

"Proactive system health monitoring is essential for maintaining product quality and production efficiency in automated manufacturing."

In automotive manufacturing, the aesthetic quality of visible components like car doors is crucial for consumer appeal. PHM systems allow for the prediction of tool wear or other degradation in hemming robots, enabling maintenance before defects occur. This ensures consistent quality and maintains production flow, especially in flexible manufacturing environments.

What This Means for Your Design

This study shows how to use data from robots that join car parts to predict when a tool might break or wear out, so you can fix it before it ruins the car's appearance or stops the factory.
