Item Výroba švových rúr malých priemerov z austenitických ocelí(University of Žilina, 2024) Bílik, Jozef; Sobota, RóbertThe article focuses on the analysis of the production process of small diameter seam tubes made of austenitic steels used in the food industry, automotive and aerospace industries, in measurement technology, heating elements, in healthcare in the production of needles for syringes, for heat exchangers designed to cool exhaust gases in the automotive industry and for fuel-oil heat exchangers used in the aerospace industry. The article deals with the production of precision seam tubes with a diameter of 6 mm and a wall thickness of 1 mm. The aim was to optimize the process using simulation using the DEFORM 3D simulation program. The solution consisted in adjusting the geometry of the beam and improving the friction ratios during the drawing.Item Využitie optickej 3D digitalizácie pri meraní rozmerov bezšvíkových oceľových rúr ťahaných za studena(University of Žilina, 2024) Morovič, Ladislav; Bílik, Jozef; Havran, FilipThe paper deals with the use of a non-contact measurement method - optical 3D digitization (active triangulation/structured light method) - in measuring the dimensions (outer and inner diameter) of seamless cold drawn steel tubes. The paper focuses on three areas of tube measurement by 3D digitization: (1) measurement of dimensions at different tube sections, (2) measurement of dirty tube surface, (3) evaluation of measured values in terms of different settings of polygonization. The results of the measured values and findings serve as useful information when deciding on the choice of 3D digitization method for measuring seamless steel tubes.
