| dc.description.abstract | Abasic study of a surface topography generated by an abrasive waterjet cutting is performed by means of the spectral analysis of these surfaces. The initial data
were acquired by using an optical profilometer MicroProf FRTin the form of 2D maps of the surfaces' heights. The basic notions of the spectral analysis applied
to the surface topography are presented. Limitations of the measurement procedure are considered. Distortions of the areal power spectral density are discussed.
An estimation of the areal power spectral density is carried out using a periodogram method combined with the Welch´s method. A comparison of surfaces
prepared by the abrasive waterjet cutting with different values of the cutting technological parameters is performed. It has been demonstrated that the areal
spectral analysis of the aforementioned surfaces offers new possibilities of their topography characterization. | cs |

| dc.description.abstract-en | Osnovna studija topografije površina nastalih rezanjem abrazivnim vodenim mlazom izrađena je uz pomoć spektralne analize tih površina. Početni podatci su
prikupljeni primjenom optičkog profilometra MicroProf FRT u obliku 2D karata visina površina. U radu se predstavljeni osnovni pojmovi spektralne analize
primijenjeni na topografiju površine. Razmotrena su ograničenja postupka mjerenja. Raspravljena su iskrivljavanja površinske gustoće spektra snage. Procjena
površinske gustoće spektra snage je obavljena pomoću metode periodograma u kombinaciji s Welchovom metodom. Uspoređene su površine dobivene
rezanjem pomoću abrazivnog vodenog mlaza uz različite vrijednosti tehnoloških parametara rezanja. Pokazano je da se spektralnom analizom navedenih
površina nude nove mogućnosti karakterizacije njihove topografije. | cs |
