摘要：
This paper faces the problem of defining stability charts when cutting Inconel 718. The method predicts the free-chatter zones in longitudinal chatter when the tool vibrates in the tangential direction. This case may occur in longitudinal turning and boring cases when the toolholder must overhang long distances. The study proposes a 1/2DOF dynamic model to implement the effect of the tangential mode on chip regeneration in the regenerative plane based on obtaining experimentally a dynamic displacement factor. On sight of simulations and experimental results, the use of the model provides a reliable approach to obtain chatter free conditions. (C) 2013 The Authors. Published by Elsevier Ltd.
