INFLUENCE OF MEASUREMENTS ON 3D ROUGHNESS PARAMETERS
Abstract
This paper presents the influence of the number of measurements in evaluating the surface quality with the help of 3D profilometry with contact. The measurements were done on a coated surface as resulted from an original laboratory technology elaborated by one of the authors. The results were useful for improving the coating technology. The surface investigation was done with the help of a 3D profilometer, for squared areas of 500 μm and here there are analyzed the average of the 25 measurements for amplitude, spatial and functional parameters. There were studied the influence of parameters’ values extracted from these measurements on the average value of each analyzed parameter and the extreme values in order to give some recommendation for the surface quality assessment of these types of surfaces. Also there were compared the results of all measurements with two restricted number of measurements on the same investigated area.
