“…An often-used principle for surface observation, with a topography resolution between 0.1 nm and 100 mm [74], is white-light interference microscopy (WLIM). By using chromatic white light (CWLIM), an inline measurement is possible due to the omission of the measurement orthogonal to the surface.…”

“…Issues of particular importance regarding the comparability of the features are: the reproducibility of the sampling schemes (quantity and location of points) and the minimization of distortions typical of the measurement principle (e.g. mechanical dilation caused by the probe tip in tactile measurements [27]). In order to help improve the comparability between the CT and the reference extracted integral features, reconstruction operations can be used.…”

This paper presents an approach to assess the quality of the data extracted with computed tomography (CT) measuring systems to perform geometrical evaluations. The approach consists in analyzing the error features introduced by the CT measuring system during the extraction operation. The analysis of the features is performed qualitatively (using graphical analysis tools) and/or quantitatively (by means of the root-mean-square deviation parameter of the error features). The approach was used to analyze four sets of measurements performed with an industrial x-ray cone beam CT measuring system. Three test parts were used in the experiments: a high accuracy manufacturing multi-wave standard, a calibrated step cylinder and a calibrated production part. The results demonstrate the usefulness of the approach to gain knowledge on CT measuring processes and improve the quality of CT geometrical evaluations. Advantages and limitations of the approach are discussed.

“…It represents the real surface measured with a tactile probing system and a correction of the extracted profile with the morphological operation erosion. The deviation of the extracted profile due to the dilation of the real surface by the sphere is eliminated [7]. In order to define new parameters to characterize and specify functional properties of surfaces, a common datum is necessary.…”

For functional properties such as gliding, sealing, assembling, adhering etc. the outer layer of the surface is the functional related surface. For the functional assessment of the surface this outer layer should be used as the reference for any functional characteristic. With the existing mean line system for the assessment of roughness and waviness, the standardized characteristics do not follow this logic. However there are valid historical reasons for the acceptance of the shortcomings of the mean line system. They are e.g. the alignment of the profile, the removal of form, the assumption of a sinusoidal structure of the waviness on the surface, and the distortion of the surface by the application of the mean line filtering process. To overcome these shortcomings morphological operations have been used to establish a new developed envelope system. In order to define new parameters to characterize and specify functional properties of surfaces, a common datum is necessary. The presented method for the alignment of datums is consistent with the algorithms used to establish datums and datum systems for workpieces, where the datum is established by the location of a tangent geometrical element such as a line, plane, cylinder etc. The orientation is usually derived by the application of the minimum zone algorithm. The benefit of the assessment of the functional properties of surfaces with morphological operations will be presented for two examples.
