| Résumé : |
Using the example of automotive paint processes, an innovative methodology for appearance measurement based on the approved confocal technology of NanoFocus AG will be presented in this paper.
The methodology allows for the description of the development of the appearance along the entire process chain. It will be shown that this methodology correlates well Wh conventional measurements. Additionally, the effect of different substrate materials and various production sites will be explained.
As the appearance of a coating is a significant quality criterion in automotive manufacturing, applying suitable and high-performance metrology solutions is crucial. Currently, appearance can only be determined at the end of the painting process after the clear coat is applied. In contrast to this, a new optical measurement device allows one to determine the appearance parameters along the entire process chain. It consists of an optical-confocal measurement system developed by NanoFocus AG' combined with an analysis methodology developed by inpro'. Measurement values can be acquired on the sheet material, after the press shop, the body shop and finally after each paint layer.
A correlation between this new technology and classical metrology methods was required in order to gain the acceptance of the automotive industry. |
