ANALYSIS OF VIBRATIONS AND MACHINED SURFACE QUALITY DURING TURNING OF Ti-6Al-4V ALLOY

<p style="text-align: justify;">This paper analyzes the influence of basic turning parameters on  vibrations and surface quality of titanium alloy Ti-6Al-4V. Due to specific mechanical properties, titanium processing often causes resonance, instability and increased roughness. The experiment was performed on a universal lathe, with varying cutting speed, feed and depth of cut, in order to <br />test different machining regimes. Vibration and roughness measurements confirmed that the best results are achieved by avoiding operating modes that cause resonance, thus reducing vibrations and improving surface quality. The obtained findings show that for a stable and precise machining process it is important to carefully select parameters and monitor vibrations in real time. In this way, the service life of the tool can be extended and a better quality of the finished product <br />can be achieved.</p>
