Analysis of surface roughness in turning process using rotating tool with chip breaker for specific shapes of automotive transmission shafts

Abstract Increasing machining productivity is the cause of constantly looking for new machining methods and methods to ensure the required quality. One of these methods is machining with rotary tool, which combines conventional cutting materials with an unconventional machining scheme. These properties allow to improve cutting conditions and thus increase productivity with preserved quality. In this paper, there is made the identification of properties and possibilities of using the rotating tool during turning. The main focus is the analysis and evaluation of technological parameters and surface quality, especially surface roughness.
