    Opis:
    The five-axis measuring systems are one of the most modern inventions in coordinate measuring technique. They are capable of performing measurements using only the rotary pairs present in their kinematic structure. This possibility is very useful because it may cause significant reduction of total measurement time and costs. However, it was noted that high values of measured workpiece’s form errors may cause significant reduction of the accuracy of a five-axis measuring system. The investigation on the relation between these two parameters was conducted in this paper and possible reasons of decrease in measurement accuracy was discussed on the example of measurements of workpieces with form errors ranging from 0,5 to 1,7 millimetre.

    Opis:
    One of the factors affecting the accuracy of Coordinate Measuring Systems is hysteresis of a probe head. It is important especially in case of touch trigger probes and should be taken into account during the determination of probing strategy. In this article, the authors try to assess how this phenomenon affects the accuracy of five axis coordinate systems which utilize articulating probe head. Such systems allow to measure point coordinates using rotary movements of the head what introduces changes to the probing process. The experiments presented in this paper are based on multiple measurements of the reference elements such as gauge blocks and standard ring.

    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:
    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.
