    The effect of burnishing process on skewness and kurtosis of the scale limited surface
    (Національний технічний університет "Харківський політехнічний інститут", 2022) Ferencsik, Viktoria; Varga, Gyula
    In this paper roughness examination and analysis on burnished low alloyed aluminium surfaces are reported, highlighting 2 parameters from the vertical deviations of the roughness profile from the mean line. From the input parameters of the burnishing process, the effect of burnishing force, feed rate, speed and number of passes are investigated. Measurements of the surface topography – before and after burnishing – are conducted on an Altisurf 520 3D measuring device. The generated and calculated values of the machined surface roughness are analysed in detail with the drawing of the conclusions as well.

    Fe investigation of surface burnishing technology abstract
    (Національний технічний університет "Харківський політехнічний інститут", 2020) Ferencsik, Viktoria; Gal, V.
    This paper investigates the finite element analysis of cold forming diamond burnishing process on aluminium alloy, where the input parameters are force, feed rate and speed, as an output parameter the changing of surface roughness is analysed. This lifetime increasing process effectively reduces roughness, improves shape correctness, and increases the hardness of the sub-surface area. Machining simulation of the turned surface before burnishing is based on the real model, corresponding to the measured values, by using DEFORM-2D software in order to validate the improvement of surface quality with numerical values too.
