Chatter stability prediction for a flexible tool-workpiece system in a turning process

Abstract

The paper focuses on the chatter stability prediction for a flexible tool-workpiece system in a turning process. The dynamic model of the turning process presented here considers two end conditions of the flexible workpiece. Chatter-free (stable) cutting parameters are obtained analytically and stability lobe diagrams (SLDs) of a turning operation are constructed using simulations to distinguish stable and unstable regions. The SLDs are constructed for a variety of tool and workpiece parameters affecting the flexibility/compliance of the tool-workpiece system to investigate the effects of these parameters on the stability of the turning process. The proposed analytical model has been validated with the turning experimental results. 2017, Springer-Verlag London.
