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.

Opis:
The article presents the validation research scheme of metrological model of coordinate measuring arm (CMA) using multifeature check. The scheme shows the comparison of the calibration results of the check using selected coordinate methods and criteria of validation. The comparison shows the insignificance of differences between the obtained results of both: metrological model of CMA and multi-position method. It evidently proves the correctness of the development of metrological model of CMA. The use of appropriate quality multifeature check also had a significant impact on the results. This check is now the most accurate measurement length check and its use for this validation process was the most suitable.

Opis:
This paper presents a new interim check device for coordinate measuring machines (CMMs) built from an AISI 1020 carbon steel bar with the incorporation of calibrated spheres. This artifact’s construction was made to make the interim checks of machines of this type faster and cheaper. Three devices were designed based on the ISO 10360-2 standard, the good practice guide No. 42 (NPL), and prominent authors’ research on the subject. The three options are presented in detail, but only one was built due to budget, size, and adaptability restrictions. An exploratory study was conducted to verify the device’s usability in two CMMs and concluded that the differences between the measurements are not significant. However, one machine had absolute variation values and a total standard deviation higher than the other, generating a larger expanded uncertainty.

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:
W ramach pracy wykonano modernizację maszyny pomiarowej typu MORA 3D, przystosowując ją do szybkiego pomiaru sprawdzianów kształtu. W tym celu wykonano interfejs komunikacyjny pomiędzy maszyną a komputerem oraz opracowano program komputerowy rejestrujący i obrabiający wyniki pomiarów. Oprogramowanie zawiera bazę obiektów mierzonych, co pozwala na szybkie wskazywanie punktów pomiarowych. Na tej podstawie automatyczne wyznaczane są osie mierzonych walców i punkty ich przecięcia. Otrzymane wyniki porównywane są z dokumentacją techniczną i przedstawiane w postaci raportu z pomiaru. Rozwiązanie takie pozwoliło na znaczne skrócenie czasu pomiaru oraz ograniczenie błędów powodowanych przez pracownika wykonującego pomiar. Dodatkowo, system umożliwia kalibrowanie końcówki pomiarowej na wzorcu kulistym.
The purpose of the work was modernisation of the MORA 3D coordinate measuring machine. The machine was adapted to fast measurements of shape. A communications interface enabling efficient connection between the machine and a computer was worked out. Moreover, a computer program recording and processing the measurement results was developed. The software contains a database of the measured objects, which allows for fast and precise choice of the measurement points. Based upon these points, the axes of the measured cylinders as well as their cross-section points are automatically determined. The obtained results are compared with the technical specifications and presented as a written report describing the measurements. The proposed solution shortens significantly the measurement time as well as reduces errors made by a personnel taking the measurements. Additionally, the system allows for calibration of a measurement tip on the ball-shaped contour master.

Opis:
In open-die forging it is state of the art to use simulation tools for creating forging plans and setpoint values for the forging press and the automated part manipulator. These forging plans define required positions and forces. Therefore, the process can be fully automated. However, even small variations of not considered influence parameters lead to different forging results and thus to a discontinuous process. Influencing factors are, e.g. material parameter deviations, uncertainties in force measurements or variations in the part temperature due to varying environmental conditions. This paper presents an approach for a fully automatic open-die forging process with respect to actual conditions, based on a parallel measurement of the workpiece geometry and temperature and a “process-real-time” adaptation on the controller system. The focus of this work is the development of a measuring strategy and an according sensor setup for the combined temperature and geometry measurement of the workpiece. In addition, the structure, the characteristic features of the components and the beam path of the sensors scanning units are shown. Furthermore, first experimental results for the alignment of the beam path are presented. In the outline, the setup and calibration strategy of the measurement system are stated.

Opis:
Reliable measurement uncertainty is a crucial part of the conformance/nonconformance decision-making process in the field of Quality Control in Manufacturing. The conventional GUM-method cannot be applied to CMM measurements primarily because of lack of an analytical relationship between the input quantities and the measurement. This paper presents calibration uncertainty analysis in commercial CMM-based Coordinate Metrology. For the case study, the hole-plate calibrated by the PTB is used as a workpiece. The paper focuses on thermo-mechanical errors which immediately affect the dimensional accuracy of manufactured parts of high-precision manufacturers. Our findings have highlighted some practical issues related to the importance of maintaining thermal equilibrium before the measurement. The authors have concluded that the thermal influence as an uncertainty contributor of CMM measurement result dominates the overall budgets for this example. The improved calibration uncertainty assessment technique considering thermal influence is described in detail for the use of a wide range of CMM users.

Opis:
The paper presents a method for estimating the uncertainty of optical coordinate measurement based on the use of information about the geometry and the size of measured object as well as information about the measurement system, i.e. maximum permissible error (MPE) of the machine, selection of a sensor, and also the required measurement accuracy, the number of operators, measurement strategy and external conditions contained in the developed uncertainty database. Estimation of uncertainty is done with the use of uncertainties of measurements of basic geometry elements determined by methods available in the Laboratory of Coordinate Metrology at Cracow University of Technology (LCM CUT) (multi-position, comparative and developed in the LCM CUT method dedicated for non-contact measurements) and then with the use of them to determine the uncertainty of a given measured object. Research presented in this paper are aimed at developing a complete database containing all information needed to estimate the measurement uncertainty of various objects, even of a very complex geometry based on previously performed measurements.
