Multi-dimensional modelling of chatter stability in parallel turning operation
Azvar, Milad and Budak, Erhan (2016) Multi-dimensional modelling of chatter stability in parallel turning operation. In: 17th International Conference on Machine Design and Production, Bursa, Turkey
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 modelled. Herein dynamics and stability of parallel turning operations including both cutter and workpiece flexibility is studied. Frequency and time domain models for multi-dimensional parallel turning have been developed where effects of process parameters on chatter behaviour are investigated.
