    Opis:
    Nowadays, coordinate measuring machines (CMM) are featured by a great degree of complexity and high accuracy of manufacturing. During use of a machine, usually after periodical maintenance it is highly recommended to perform a verification test according to the same procedures as a standard verification test, including a difference that performance conformity is checked with user’s declaration. Periodical verification should be performed as often as it comes from a user’s experience and after every interference influencing mechanical and electronic systems of a CMM that could potentially cause a change in its accuracy parameters. The best solution is employing for that purpose an independent accredited laboratory that is featured by high competence and experience. In the paper rules of acceptance and periodical verifications are described, sources of measurement errors resulting from CMM imperfections are presented as well as examples of results for specific measurement devices installed in industry were shown.

    Opis:
    The subject of the article is an attempt to determine the impact of the applied measurement strategy on the accuracy of the measurement result. This problem is particularly crucial when measuring large objects. In these cases, it is not always possible to provide ideal conditions for the submission of particular scans. It is necessary to adjust the strategy to specific imposed conditions defined by the geometry of the object and to the time frame of the measurement itself. With regard to the above, an attempt was made to carry out a series of accuracy studies testing the structural light scanner while measuring elements of overall dimensions greater than the measuring capacity of the scanner. At the same time, various potential measuring strategies were simulated in practical applications. Our studies were conducted using a pre-designed test template with a defined distribution pattern of reference points and geometrical elements. Moreover, in order to make an in-depth investigation of the issue, some trials were undertaken with the use of limiting parameters. That means the scanner had both an excess and shortage of information required for a correct assembly of scans. Those scopes were taken into consideration in the study in order to use the acquired knowledge in practical measuring applications. Furthermore, conclusions from the conducted studies indicate peaks and troughs of respective measuring strategies with special care for determining relationships among the used strategies and the measuring accuracy parameters.
