Tunç, Lütfi Taner and Budak, Erhan (2011) Effect of cutting conditions and tool geometry on process damping in machining. In: 4th International Conference on Manufacturing Engineering (ICMEN2011), Thessaloniki, Greece
Process damping can be a significant source of enhanced stability in metal cutting operations especially at low cutting speeds. However, it is usually ignored in stability analysis since models and methods on prediction and identification of process damping are very limited. In this study, the effects of cutting conditions and tool geometry on process stability in turning and milling are investigated. The previously developed models by the authors are used in simulations to demonstrate conditions for increased process damping, and thus chatter stability. Some representative cases are presented and verified by experimental data and conclusions are derived.
