DetectiNG appearance defects on stamped parts
Specialists mainly use subjective sensory methods to detect appearance defects. These methods are time-consuming and lead to a number of errors.
The objective of this project is to find an optical, non-destructive inspection tool that can almost instantly analyse and quantify all the appearance defects on a stamped part. A non-specialist operator in the field would be able to carry out these tests, which would be definitive.
This work has led to the design of a system based on axial chromatism coupled with an algorithm for processing and classifying the detected defects.
This objective analytical method and the intelligent algorithm that has been developed can reduce inspection times and associated errors.
