Investigation and Analysis of Chatter Vibration in Centerless Bar Turning Machine
Chatter vibrations are present in almost all cutting operations and they are the major obstacles in achieving desired surface finish. Chatter vibrations are the self excited vibrations, which has an adverse effect on surface roughness, dimensional accuracy of the machined components. This paper investigates the occurrence of regenerative chatter vibrations in centerless bar turning operation. T...
متن کاملApplication of Spindle Speed Variation for Chatter Suppression in Turning
In the present paper the chatter instability of variable speed machining is studied. Though, there exist numerical methods for the computation of the stability lobes for variable speed machining, especially in turning processes the potential of an active spindle speed variation for chatter suppression is mostly unexploited. In the case of a slowly time-varying spindle speed, which is practicabl...
متن کاملMulti-dimensional Modelling of Chatter Stability in Parallel Turning Operation
Recently, use of parallel turning operations has been increasing due to the potential they offer for improved material removal rate using multiple cutting tools. However, chatter vibrations resulting from process instability may limit the productivity in these operations. In order to determine favourable conditions for increased stability, dynamics of parallel turning operations must be modelle...

متن کاملExperimental Passive Suppression of the Regenerative Chatter Phenomenon by Variation of the Frequency and Amplitude of the Spindle Motor Excitation in Turning
The suppression of the regenerative chatter phenomenon in turning process via the variation of the frequency and amplitude of the spindle motor excitation is carried out in this research. A programmable inverter is employed for variable periodic excitation of the spindle motor. A set of turning experiments is designed and performed on a number of conical work pieces both in constant spindle spe...
