Abstract

Multi-cutter turning systems offer huge potential to raise productivity in the manufacturing process of cylindrical parts. The application of a multi-cutter turning head increases cutting performance, material removal rate, since the advance rate is multiplied by the number of cutters involved. Another reason to apply the multi-cutter turning technology is to ensure high feasible accuracy, which is one of the most important quality measures of cutting operations. Furthermore, adverse chatter vibrations caused by the regenerative effect can also be eliminated through the application of optimized multi-cutters. The aim of this study is to investigate the stability properties of multi-cutter turning operations. It is shown that the application of dynamically uncoupled cutters with identical dynamic properties will not improve the stability properties of the system, however, the usage of cutters with different modal parameters - especially finding the optimal ratio of stiffness values of different cutters - will expand stable area in the stability charts, thus ensuring more flexibility and a wider range of stable operational parameters available for the machinist. This study proves that the stability properties of a multi-cutter turning system using dynamically uncoupled cutters are equal to the stability properties of a system using a single cutter with many degrees of freedom.
