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 Theoretical value and experimental study of arithmetic mean deviation in rotational turning(Національний технічний університет "Харківський політехнічний інститут", 2022) Sztankovics, István; Kundrak, JanosThe calculation method of the Arithmetic Mean Deviation (Ra) is presented for rotational turning. The necessary equations for the calculation of Ra are given beginning from the equation of the cut surface theoretical profile, and we determine the theoretical values in the studied range of the technological parameters. Cutting experiments with these data were performed and the roughness values of the machined surfaces were measured. Then we carried out a comparative analysis of the measured and the calculated values ofthe arithmetic mean deviation.
