The thesis will, in its theoretical part, present the types of cutting tool materials, the types of coatings for cutting tools, chip breakers, and the tool geometry for longitudinal turning. Subsequently, the testing environment will be described, including the selected machine, the workpiece material, and other auxiliary equipment. The study of tool wear progression and the formation of chip shape under different cutting speeds will be presented. The research process will be documented using visual and measurement methodologies, based on which calculations of productivity and machining costs will be performed. These results and findings will serve as a guide for selecting the tested tool for longitudinal turning, which is the most economically optimal for the given machining process.
