Abstract: This paper deals with an experiment with the material of AISI 309 with thickness of 15 mm, to carry out the research into material vibration phenomena as the tool of the online controlling of surface texture created by abrasive waterjet. Vibrations of the material were collected by accelerometers of PCB IMI 607 A11. The generated topography on material was measured with optical profilometer MicroProf FRT and the data were confronted with the resultant vibration parameters. A new parameter VRa [g] is proposed to detect the surface texture by vibration. New equations for detecting the surface quality were derived.
