Abstract
Light alloys, such as Aluminium or Titanium based alloys are frequently used in the aircraft industry. In the particular case of Ti alloys, they are usually commonly turned for obtaining strategic airships parts under rigorous quality requirements, in order guarantee the functionality of the workpiece design conditions. So, the analysis of the finishing quality of the turned pieces is essential in the quality control process. In this paper a study of the finishing quality of dry turned UNS R56400 Ti alloy has been achieved on the basis of the analysis of workpiece surface roughness, Ra, as a function of cutting parameters, such as feed and cutting speed. In parallel, a comparative analysis of the influence of the tool coating has been achieved. The obtained results have shown that coated tools cause a worse surface finishing quality.
