With the increase in the use of difficult to machine and hard materials, it is necessary to find new productive ways of machining these materials. Among these technologies, we can also include forced tool rotation turning (ADRT), the easy deployment of which is made possible by the development of CNC machine tools. This non-standard kinematic structure of machining brings many advantages, mainly in increased tool life and lower temperatures in the cutting zone. This technology can be used for the production of parts in the automotive and aerospace industries. In the experiment of the paper, the dependence of surface roughness on cutting speed in turning with forced tool rotation was investigated. A monolithic tool was designed and used for the experiments, which was predicted to have higher strength and reduced recess formation compared to a tool with an interchangeable cutting insert. The measured roughness of the machined materials reached relatively low values, which could be further improved with improvements in the overall process technology system. |
