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 5-axis systems, especially those that use in their kinematic chain both prismatic joints and revolute kinematic pairs are gaining popularity in many scientific disciplines with manufacturing, metrology and robotics at the forefront. This is therefore important to undertake research aiming in identification of sources of inaccuracies in their functioning and investigation on possibility of eliminating or compensating them. A significant impact on 5-axis kinematic structures accuracy may be assigned to parameters associated with the stabilization of the machine position and angular position, such as position stabilization time, position overshoot and drift of positioning accuracy. These parameters are well described in ISO 9283 standard related to performance criteria and test methods for industrial robots. The methodology presented in this standard is adapted for testing the impact of mentioned parameters for functioning of 5-axis kinematic structures other than industrial robots, which mainly include five-axis coordinate measuring systems and machine tools. A series of experiments performed on five-axis coordinate measuring system is presented in this paper, their results are assessed in a quantitative manner and basing on them a general algorithm for assessing the significance of impact of position stabilization parameters on functioning of the manipulator is proposed.

Opis:: W pracy przedstawiono wybrane zagadnienia dotyczące oceny jakości procesów technologicznych oraz wyrobów. Przedstawiono sposoby oceny jakości za pomocą wskaźników zdolności maszyn i urządzeń na bazie metodyki SPC. Zamieszczono także ocenę dokładności wyrobów z wykorzystaniem rentgenowskiej tomografii komputerowej. Do oceny zaproponowano wzorce przestrzenne oraz strategię umożliwiającą porównanie urządzeń pomiarowych względem siebie i ocenę dokładności odwzorowania badanych wyrobów.
Chosen aspects of quality estimation of technological processes and products were presented in this paper. Methods of quality estimation which use process and machine capability indices according to SPC framework were also presented. Next part of paper concerns topics connected with products accuracy evaluation using Computed Tomography. Spatial standards were proposed to use in accuracy evaluation.

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.
