    Opis:
    Manufacture of aircraft gearbox elements requires control of gear geometric parameters at different stages of technological process. In case of measurement of gear wheels using modern technologies based on numerical machines, measurement process is based on processing of numerical data obtained by measurement using coordinate measuring machines. The goal of this paper is to present the measurement process of gears, using coordinated optical scanner ATOS II TripleScan by GOM, equipped with a turntable. The aim of this study is to develop and execute the analysis accuracy of the geometry of the gear of aeronautical dual-power path gear after the roughing operation using optical coordinate measuring methods. Executed research will enable the detection of errors occurring in the machining process and to determine the value of founded the machining allowance finishing in relation to the CAD model. Using coordinate measuring technique, one can specify a set of methods and procedures for the designation of the complex dimensions of physical objects and transform them into a computer program space of coordinate measuring devices. On this basis, it is possible to determine the accuracy of the gear wheel as the workpiece prior to heat treatment. The results will be the basis to determine the effect of heat treatment on changes in the geometry of the gear and the benchmark for determining the correctness of the finishing.

    Opis:
    Properly prepared and carried out the measurement process of bevel gears determines its accuracy and productivity. This also has an influence on the final accuracy of bevel gears and the production costs of aeronautical gearbox. In the process of assessing the accuracy of manufacturing, majority of manufacturers of bevel gears use specialized contact coordinate measuring machines. The application of such machines as well as specialized programs dedicated to measuring the geometry of bevel gears are authoritative but in turns this requires substantial financial resources for the purchase of machinery. Thereby, this causes the limitation only of the gear assortment. Therefore, this article depicts different perspective on measurements of bevel gears using a universal measuring device, which is an optical 3D scanner ATOSII Triple Scan. Due to the use of the optical scanner ATOS II Triple Scan in measurement process, it was necessary to develop a methodology dealing with the process of assessing and accuracy, in order to achieve the desired results of measurement. This need arises from the fact that the optical scanner ATOS is not dedicated, specialized device for measuring gears. Despite of this fact, maintaining the appropriate measurement procedures and a proper preparation of the measured model allows for rapid and accurate assessment of the accuracy ofproduction. The article presents the analysis of conditions and developed rules concerning the preparation of a model for measurement. It also contains hints and a description of the measurement process. Furthermore, it depicts the rules specifying the interpretation of measurement results as well as the technical rules of their realization.

    Opis:
    Designing and manufacturing of aeronautic bevel gearboxes is a complicated and time-consuming process because of complex kinematics of the machining process as well as numbers of manufacturing methods. Machine manufacturers usually provide algorithms used in manufacture process. This requires substantial financial resources and, in consequence, it increases the costs of production. Using other commonly available calculation algorithm requires a lot of studies to verify whether the proposed gearbox works correctly. In order to reduce the manufacturing costs of prototypes, it is possible to use Rapid Prototyping methods. Using both Rapid Prototyping techniques and coordinate optical measurements enables to verify the correctness of assumptions made in the initial stage of product designing. This approach reduces significantly both prototyping time and manufacturing costs. In order to ensure the effectiveness of prototyping process, it is essential to provide the accuracy of manufactured prototypes. That is the reason why it is necessary to determine manufacturing methods that will ensure the highest geometric accuracy. The study presents the modelling and manufacturing process of aeronautic bevel gear of demonstrator taking into consideration the accuracy of selected Rapid Prototyping methods. The gear modelling is based on machining simulation method conducted in Autodesk Inventor. The measurement results are shown in displacement maps obtained with an optical scanner Atos II Triple Scan and universal GOM Inspect Professional software, which determines the prototype accuracy in relation to 3D-CAD models.
