Analysis of the effect of burnishing process on skewness and kurtosis of the scale limited surface

Abstract

In the publication the effect of the surface burnishing process on the skewness and kurtosis of the scale limited surface 3D roughness parameters for EN AW-2011 shaft workpieces is discussed. The article presents the burnishing parameters (burnishing force, feed, speed, number of passes) examined at 3 levels and their effect on 2 microtopographic features. The purpose of the research work is to describe how these characteristics correlate with each other, thereby promoting the more effective applicability of the procedure in industrial practice. Measurement of the surface topography – before and after burnishing on 3 areas by rotated 120°- were implemented with Altisurf 520 3D surface topography measuring device.
