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.Item Stratégie frézovania tenkostenných komponentov z ťažkoobrobiteľného materiálu(University of Žilina, 2023) Hrbál, Jakub; Vozár, Marek; Pätoprstý, Boris; Buranský, IvanThe paper deals with the issue of the influence of machining strategies and tool parameters on the quality of the machined surface of thin-walled parts made by WAAM technology. The current state of machining thin walled parts is complemented by utting tools in terms of materials, geometry, and tool wear. From the point of view of surface integrity, the roughness and flatness of machined thin-walled parts made of Inconel 718 nickel alloy material will be observed. The machining strategy and cutting tool geometry were designed by experimental machining. The results of the experiment are presented in the conclusion. Achieved experimental results are a contribution to the efforts to expand the knowledge on the topic of machining thin-walled parts.
