Документ Analytical analysis of the theoretical surface roughness in the case of burnishing of cylindrical workpiece(Національний технічний університет "Харківський політехнічний інститут", 2023) Ferencsik, ViktoriaIn the last decade, ensuring the highest possible surface quality of manufactured parts has been given a major priority, so more and more emphasis is being placed on the examination and development of finishing treatments that can effectively ensure increasingly stringent surface roughness. For this purpose, diamond burnishing - which is a widely used cold plastic technology - can be used productively as it can improve the surface roughness of the material. But even though due to the development of engineering technology, new possibilities and methods are constantly being developed to examine individual material structure changes, the ability to plan the surface roughness is very difficult. This paper focused on the determination of theoretical roughness to establish a mathematical model that can predict and analyse the relationship between experimental process parameters and surface roughness parameters. To validate the model, real experiments were performed, where the surface roughness were measured before and after the application of burnishing process on low alloyed aluminium shaft pieces.
