  Image-based measurement of the dimensions and of the axis straightness of hot forgings
  journal article in Web of Science
  Non-contact measurement of shapes and dimensions is currently quite a common issue. A lot of systems with different speeds and accuracies are in the market. Measurement of high temperature objects is, however, a very special task which ensures a specific solution. This paper presents a measurement system composed of two high resolution single-lens reflex cameras and a software application, which is designed for the fast measurement of shapes and dimensions of rotationally symmetric forgings. The software computes the length, diameter, and straightness of the axis, based on a 3D model constructed from four boundary curves of the forging captured in two images. Experimental measurements have shown an error of up to 2% for the length measurement and 1% for the diameter measurement. Results are available in a few seconds. The proposed measurement approach based on boundary curves shows a great potential for practical use in forging plants.

  The additive manufacturing of metallic parts by means of selective laser melting is an emerging technology, the development of which is currently of great interest. The quality of the parts produced is evaluated mainly in terms of their mechanical properties, dimensional accuracy, and the homogeneity of the material. Because it is virtually impossible to produce parts without any internal porosity using powder-based additive manufacturing processes, measuring the porosity is critically important to optimizing the processing parameters. X-ray computed tomography is currently the only way used to measure the distribution of pores non-destructively and it can also measure the density and dimensional accuracy. Many studies have presented results of porosity measurements made using CT, but no standard methodology for the making of measurements and processing of data currently exists. The choice of parameters used for measurement and processing can have a significant impact on the results. This study focuses on the effect of voxel resolution on the resulting porosity number and discusses the possibilities for determining the threshold value for detecting pores. All the results presented in this study were obtained by analyzing the sample produced by selective laser melting technology from AlCu2Mg1.5Ni alloy.

  The paper deals with verification of stress-strain results of finite element analysis (FEA) of the towing hitch for passenger's car by experimental measurement. For the purpose of experimental measurement a stand, which allows adjustment and monitoring of loading forces of the towing ball in two axes, has been designed. Monitoring of loading forces was performed by strain gauge force transducers and CatmanEasy software. Static deformations were measured by industrial photogrammetric system Tritop. 3D virtual model of towing hitch for FEA was created by reverse engineering using 3D scanner Atos III Triple Scan. The paper presents results of FEA in comparison with the results of photogrammetric measurements performed on an experimental stand.

  This paper presents an approach to the axis straightness measurement of cylindrical forgings and shows results of the first experimental measurement in laboratory conditions. The proposed image-based system is based on the assumption that actual shape of the cylindrical forging axis can be determined (in the simplest case) from four boundary curves which lie in two mutually perpendicular planes. Four boundary curves can be obtained by detecting forging edges in two images. The measurement approach was tested in laboratory conditions on the cylindrical rod sample of room temperatures with length of 700 mm and diameter of 45 mm. Results of image-based measurement ware compared with results of measurement by industrial 3D scanner Atos III Triple Scan. In the case of maximum deflection size, the difference between both measurement methods is less than 0.3 mm; in the case of angle of maximal deflection is less than 3 degrees. Despite the positive forecasts, additional measurements must be performed to determine the repeatability of the measurement on different sized samples. Further work will be devoted to testing and optimizing the measurement of hot forgings.

  The motivation of this work was to find a suitable 3D scanner for human body parts digitalization in the field of prosthetics and orthotics. The main project objective is to compare the three hand-held portable scanners (two optical and one laser) and two optical tripod scanners. The comparison was made with respect of scanning detail, simplicity of operation and ability to scan directly on the human body.
