The paper reports about an experimental research aiming to investigate the mutual relationships between tool wear and power spectrum of the flexural vibrations of the tool, during cutting, in turning operations. The methodology of machining tests for data collection, the software performing spectral analysis and the results of the first series of tests are described and discussed. Further development in this research field are then proposed.
