MEASUREMENT PROCEDURES AND EVALUATIONS METHODS FOR THE EXTRACTION AND ASSESSMENT OF FUNCTIONAL FEATURES OF MICROSTRUCTURED SURFACES

Wito Hartmann, Andreas Loderer

Abstract

The paper describes an approach how to measure function-oriented with appropriate measurement technology and evaluation methods. At first important features of the surface, which have a large influence on the functional behaviour, are determined based on a physical-mathematical model of the function. Then – adapted to the measuring task – it is described how to measure these features starting with the selection of suitable measurement procedures (optical/tactile, 2D/3D, multi-scale data fusion). Moreover, the evaluation of the measurement values is also crucial. Automated evaluation procedures based on segmentation techniques and autocorrelation methods were presented using examples of microstructures for the improvement of sliding and ink transfer for printing machines. These procedures allow extracting important functional properties of the measured 3D surface and their quantitative evaluation.
