Abstract

Multi-cutter turning systems bear huge potential to increase the machining productivity of cylindrical parts. The reason for this is that the application of multi-cutter turning heads enables to raise the material removal rate, since the rate is multiplied by the number of cutters involved. Multi-cutter turning technology is not only applied to increase cutting performance but also to ensure highest possible accuracy, which is one of the most important quality measures for cutting technologies. In this study, a further benefit of multi-cutter turning operations is shown, which is the possible elimination of adverse chatter vibrations by means of optimal tuning of system parameters. Based on numerical stability calculations, the stable machining parameter region can significantly be expanded for dynamically uncoupled and optimally tuned cutters. Results have been validated by measurements.
