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 limited. In this study, the effects of cutting conditions and tool geometry on process stability in turning and milling are investigated through simulations. The previously developed models by the authors are used in simulations to demonstrate conditions for enhanced process damping, and thus chatter stability. Some representative cases are presented and verified by experimental data and conclusions are derived. Cutting conditions and tool geometry for enhanced chatter stability due to increased process damping are presented.
