Abstract

This contribution presents a new algorithm to extract a measure of the quality of honed cylinder bores based on 2D intensity or topography data, enabling thus an objective assessment of their surface texture. The method is based on an adaptive separation of the surface data into two complementary components-the groove texture and the background data. Following, from these separation results, a scalar feature is computed that describes the texture quality compactly and reliably. Based on a series of fax film replicas of real honing textures showing different degrees of quality, the principle of the algorithm is illustrated. Moreover, the usefulness of the proposed approach is demonstrated by comparing classification results based on the new measure with ratings of experts. In all cases, a correct class assignment could be achieved.
