Opis:: Coordinate metrology determines nowadays the relevant directions of development in automated measuring systems and quality management in the field of machine industry. The essential problem of coordinate measuring technique application is the issue of accuracy assessment of performed measurements. This paper describes the development of coordinate systems modelling as a new field of assessing the accuracy of measurements carried out in a quasi-real time. The practical solutions of the so-called virtual machines and virtual measuring systems were described along with the results of their evaluation and validation methodology based on a comparison of obtained results with the results produced by the typical methods of coordinate measurements accuracy assessment.

Opis:: The measurements of solids of revolution are one of the most common task in industrial practice. Therefore it is not surprising, that new solutions dedicated to improve accuracy and acceleration of measurements of rotational components are emerging. In this group, the new generation of articulating probing systems (with ability of continuous indexation) is worth mentioning. These probing devices combined with standard CMM forms the five-axis coordinate system. Such solution results in measurements acceleration and also improve measurement repeatability. Studies on this type of probing systems proved that their accuracy depends strongly on the angular orientation of probing system used during measurement. Therefore authors developed model that allows simulation of probing system errors for any orientation. This article describes an attempt to use the model to find the configuration of the probing system that would provide the highest accuracy for rotational elements measurements. The simulation results are compared to the real measurements of standard elements performed on five axis measuring system. Described prediction method could have a beneficial effect on improving the accuracy of measurements and, as a result, on reducing production costs by minimizing the risk of erroneous decision on the conformity of products with their geometric specifications.

Computed tomography (CT), after its dynamical development for medical requirements recently starts to appear in an area of industrial applications. It enables not only to determine dimensions of objects made of metal, plastics and different kinds of composed materials but also to defect internal defects of the material. This paper describes concepts of CT measurements. The main construction units of tomographs are characterized and the examples of tomographs of different firms and their applications are given. The accuracy and calibration problems are also shortly discussed. At the and the concepts of home - made computed tomograph for industrial applications are also presented.
