Modelling Machining Dynamics Including Damping in the Tool-Workpiece Interface

摘要: Machining instability, namely chatter, occurs due to the interaction between structural dynamics and cutting process. The process damping generated at tool-workpiece interface is an important parameter of that interaction. A significant enhancement chatter simulation model in milling presented. It includes tracking interference tool flank wavy surface, which source damping. Results runs performed determine limits stability are presented for sharp tools as well with various amount wear. phase relationship ploughing force vibrations explained using these simulations. also shown improved accurately predicts increase limit wear, effect wave length machined surface undulations on Cutting tests aluminum confirmed results.
