Opis:: Non-invasive method of the measurement and identification of shape and geometrical characteristics of measured detail based on the computer tomograph is widely applied in medicine with high efficiency. The paper is aimed at presenting the metrological analysis of the accuracy of shape reproduction. The examined shape was described due to the tomography and compared to the results of coordinate measurement. The comparative accuracy analysis of the tomography was performed for the typical details, as well as for the masters made with high accuracy. Using the results of the analysis, the respective models of measured details were created and used as a nominal in the further investigations. The results of the measurement with tomography were compared with the results achieved from the measurement by means of typical coordinate measuring machines and by means of 3D measurement optical scanner. Analysis of the gained values of the form deviations and important geometrical characteristics enabled to perform complex analysis of the shape reproduction of the examined detail with the method of computer tomography. The main purpose of the performed researches was the determination of the reproduction accuracy of surface measured with non-invasive computer tomography method. The investigations and analysis have been performed with the following equipment: computer tomograph, 3D printer and coordinate optical scanner supported with specialized software for advanced CAD data analysis.

Opis:: Manufacturing of aircraft engine turbine blades requires control of blade geometric parameters at different stages of technological process. Acceleration and automation of measurement process can affect the duration of the finished item production. Modern technologies for measurement of aircraft engine turbine blades are based on numerical machines - measurement process is based on processing of numerical data obtained by measurement using coordinate measuring machines. The paper presents the opportunity of automation of aircraft engine turbine blades measurements using scanner ATOS II Triple Scan with blue light source technology. Coordinate measuring technique allows to specify full methodology for designation of complex dimensions of physical objects and transform them into a computer program space of coordinate measuring devices. Presented paper includes capabilities of device used in the study to improve the measurement process in the technological and economical aspects. Another issue described in the paper is impact of measurement performance in automatic mode on the quality of performance – the numerical model of surface, from the standpoint of accuracy and number of collected data points in time. The paper includes an analysis of conditions related to the measurement works, such as the process of preparing the model, measurement equipment and data processing capacity. As the result methodology for automated scanning measurements of aircraft engine turbine blades will be presented.

Innovation technologies for measurement of aircraft engine turbine blades are based on coordinate numerical machines – measurement process is based on processing of numerical data obtained by measurement using coordinate measuring machines. The paper presents the opportunity of analysis of dimensional accuracy of aircraft engine turbine blades measurements using coordinate measuring machine (CMM). Coordinate measuring machine allows specifying full methodology for designation of complex dimensions of physical objects (blade of aircraft engine) and transforming them into a computer program space of coordinate measuring devices. Presented paper includes capabilities of device used in the study to improve the measurement process and blades geometry analysis in the technological and economical aspects. Another issue described in the paper is impact of measurement performance in automatic mode on the quality of performance – the numerical model of geometry, from the standpoint of accuracy and number of collected data points in time. Measurements using a coordinate measuring machine are among the most accurate methods of measuring. The paper includes an analysis of conditions related to the measurement works, such as the process of preparing the model, measurement equipment and data processing capacity.

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.

Opis:: The aim of this paper is to present methods of estimating and guidelines for verifying the accuracy of optical photogrammetric measuring systems, using for measurement of large size elements. Measuring systems applied to measure workpieces of a large size which often reach more than 10000mm require use of appropriate standards. Those standards provided by the manufacturer of photogrammetric systems are certified and are inspected annually. To make sure that these systems work properly there was developed a special standard VDI / VDE 2634, "Optical 3D measuring systems. Imaging systems with point - by - point probing. " According to recommendations described in this standard research on accuracy of photogrametric measuring system was conducted using K class gauge blocks dedicated to calibrate and test accuracy of classic CMMs. The paper presents results of research of estimation the actual error of indication for size measurement MPE_E for photogrammetric coordinate measuring system TRITOP.
