Prediction of chatter vibration in milling

Avoiding vibration during processing is an important issue for industry. A numerical approach to the prediction of chattering vibration requires several numerical models, including dynamic models of the workpiece and tool, cutting interaction laws, and surface representations. The resulting model is a trade-off between the complexity of the previously mentioned elements in the solution strategy for a given equation of motion. This paper describes a case study of predicting chattering vibration in milling using an instantaneous contact force model, which is one of the methods for cutting force simulation.
