“…Measuring methods, due to the contact of the measuring instrument with the tested object, can be divided into contact and non-contact [23,24]. Contact methods include traditional measurements with CMMs, where the measurement is realized by the point of contact between the tip of the measuring head (usually spherical) and the surface to be measured [25].…”

This paper presents geometric analyses of welded frames after free relaxing and vibratory stress relief (VSR). The tested frames were components of a prototype packaging machine. Two types of relaxation were carried out to remove stresses introduced as a result of the welding process. One of the frames was subjected to free relaxation, while the other one was subjected to accelerated vibration relaxation. Detection of the frame geometry changes was performed using a photogrammetric system. In addition, an evaluation of the geometry change was conducted for fifteen variants of a steel frame support. A comparative analysis of the geometric deviations of the frames after free and vibratory stress relief confirmed the assumption that the frame post vibration stress relief better reproduces the nominal dimensions. Nevertheless, it should be emphasized that after vibratory stress relief, the frame is not subject to further deformation, which is a desirable effect. In the case of free relaxing, the frame undergoes dimensional changes in a random manner. In summary, carrying out accelerated vibratory stress relief allows for control of spontaneous dimensional changes in the designed frame of a packaging machine resulting from spontaneous relaxation of stresses arising from the welding process. The shortening of the relaxation process of the welded frame is also an unquestionable advantage.

This paper presents geometric analyses of welded frames after free relaxing and vibratory stress relief (VSR). Respected frames were tested components of a prototype packaging machine. Two types of relaxation were carried out to remove stresses introduced as a result of welding process. One of the frame was subjected to free relaxing, while the other one to accelerated vibration relaxing. Detection of the frame geometry changes was performed using a photogrammetric system. In addition, an evaluation of the geometry change was conducted for fifteen variants of steel frame support. A comparative analysis of the geometric deviations of the frames after free and vibratory stress relief confirmed the assumption that the frame after vibration stress relief better reproduces the nominal dimensions.

“…Nowadays, non-contact measuring systems are raising in engineering metrology due to their efficiency when measuring a parts that could not be measured using coordinate measuring machines or could be measured very complicated. In contrast to the coordinate measuring machines are the optical scanners, for instance, less appropriate to play so wide and high precise metrological role [8]. On the other hand there are applications where is more useful to use optical non-contact measuring systems instead of contact methods [9].…”

The main paper idea was compared three methods (Contact CenterMax and contactless ATOS TripleScan II, Metrotom 1500) for data acquisition to the output characteristics of steel drawing tubes. Outer and internal diameters, eccentricity and ovality were measured. Steel tubes produced by drawing should accomplish shape and dimensional characteristics. These can be measured by various contact and contactless methods. Each of these methods have advantages and disadvantages. The computed tomography advantages are, that we obtain both outer and inner tube shapes. Output is a 3D model from which you can get the elements to evaluate the characteristics. The data acquisition is limited by wall thickness and material density and that is disadvantage. The 3D scanner advantages are, that we obtain outer tube shapes with different diameters and wall thickness regardless of material density. Output is a 3D model. Problem is to obtain data about complex internal shape limited by tube length and diameter and that is the disadvantage. The advantage of acquiring data by contact method is that we obtain both external and internal tube shape, without thickness wall, diameter or material density limitation. The disadvantage is that we don´t obtain a 3D model of tube, but only a spot-scanned elements.
