Abstract

The dynamical phenomena associated to machine tools’ functioning are determined by the interaction between the equipment’s elastic system and the cutting
process. Vibration occurrence is inherent, especially due to transitory processes (start/stop, motion sense reversal, etc.). In this paper, we analysed the feed kinematical chain running with slow sliding speeds, in the context of the frictional process complexity. The speed minimum value enabling the sledge continuous motion and, at the same time, avoiding the appearance of the self-excited vibrations (in connection to the well-known “stick-slip” phenomenon) was studied.
