RT Journal Article SR Electronic A1 Fabian, Stanislav A1 Salokyová, Štefánia A1 Jacko, Patrik T1 Experimental verification of the frequency spectrum of unwears and wears guidance tube on the technological head vibrations creation in the production system with AWJ technology JF Manufacturing Technology Journal YR 2012 VO 12 IS 2 SP 105 OP 108 DO 10.21062/ujep/x.2012/a/1213-2489/MT/12/2/105 UL https://journalmt.com/artkey/mft-201202-0004.php AB The solution and evaluation of the production system (PS) operation with water jet technology was addressed in more works. It is appropriate to complement this knowledge from works focused on investigation of the other factors effect which affecting the emergence and spread of technological head vibrations, affecting reliability, durability, economic efficiency and operation safe of PS with water jet technology. The article presents experimental investigation results of the vibration acceleration frequency spectrums during cutting steel by unwear and wear rectifying tube with water jet technology. The vibrations size was assessed by two basic vibrations parameters - vibrations frequency and vibration acceleration amplitude.
