Turning is one of the wide spread manufacturing technologies used in industrial production. Experiment was focused on researching of influence of various cutting conditions on machined surface. Main aim of this article is comparison of surface roughness parameters Ra and Rz depending on feed rate and tool nose radius. Investigation and finding of optimal cutting conditions is necessary for economy of manufacturing organization. Despite extensive research carried out in the area of turning, there is always room for new research.
