SIMULATION AND EXPERIMENTAL RESULTS ON THE TEMPERATURE DURING TURNING PROCESS OF COMMERCIALLY PURE TITANIUM
The turning of pure titanium can be considered, from point of view of machining, a very difficult material, due to low thermal conductivity and thermal diffusivity, but not only. For this reason temperature during the turning process is a very important task in the factors evaluation of the turning process, and can affect the tool wear and sometimes can produce structural modification.
In this paper the temperature during the turning process of pure titanium is analysed, using two methods, simulation and experimental determinations. In order to obtain the correct results, for the simulation and experiments, the same cutting parameters were used, and also, in the case of experiments, the emissivity of pure titanium was determined.
