Документ Fem analysis of the burnishing process of X5CrNi18-10 stainless steel(Національний технічний університет "Харківський політехнічний інститут", 2022) Sztankovics, István; Varga, GyulaThe burnishing process can improve the surface roughness of machined parts, while having an advantageous effect on the properties of the layer below the surface. In this paper the effect of the surface speed, the feed rate and pressing force are analysed with Finite Element Method. The affected width and depth were analysed during one pass of the burnishing tool. We also examined the highest pressure and the stress distribution of the surface layer. The values of the studied parameters were chosen according to the “Design of Experiments” method. Equations determining the studied properties were also given.Документ Preliminary analysis of surface topography in tangential turning(Національний технічний університет "Харківський політехнічний інститут", 2022) Sztankovics, I.; Pásztor, I.Among the productivity-increasing high feed turning procedures, the tangential turning is studied in this paper. Our main focus was a preliminary analysis of the machined surface topography by the DoE method. To achieve this goal 2 kinds of cutting speed, feed and depth of cut were chosen as factors which are influence the surface topography, resulting in 8 experimental setups. After the cutting experiments 2D profile measurements and shape error measurements were done. In this paper the Ra, Rz parameters of the roughness profile, Wa, Wz parameters of the waviness profile and the straightness error were analysed in more depth. We determined their alteration as a function of the studied parameters and designated our further research directions.
