TL;DR: In this paper, a comparator was developed for the measurement of both diameter and form of cylinders, spheres and cubes in a single specimen setting using a contact probe technique, and the measurement volume is mm and the uncertainty is 0.01 per 100 mm length for calibrations of outer diameters, form and parallelism.

TL;DR: In this paper, an uncertainty analysis for roundness measurements on a glass hemisphere was performed using the spindle measuring instrument Talyrond 73 for the correction of spindle errors, a multi-step error separation technique with ten steps was used Various input quantities were investigated such as the form deviations of the hemisphere, the characteristic of the probing system and thermal drift effects.

TL;DR: This paper presents procedures and standards for the testing of tactile and optical microsensors and micro-computed tomography (micro-CT) systems for coordinate metrology and assess local and global sensor characteristics.

TL;DR: In this article, procedures and standards to test tactile and optical microsensors and micro-computed tomography (CT) systems are presented, similar to the established tests for classical coordinate measuring machines and assess local and global sensor characteristics.

TL;DR: In this article, a geometrical standard for testing X-ray micro-computertomography measuring systems (μCT) and methods for manufacturing and calibration are described, which enables the testing of μCT measuring systems to use test procedures of classical coordinate measurement technique according to ISO 10360 resp. VDI/VDE 2617 as well as the nominal actual comparison of µCT data against reference data.
