Popis:	Milling is a complicated metal machining process characterized by a rotating tool that produces continuously varying chip loads, simultaneous multi-flute contact, and interrupted cuts. The complex kinematic and dynamic nature of the process in conjunction with the highly nonlinear workpiece material behaviors poses unique challenges for analyses. In this paper, a three-dimensional explicit dynamic Lagrangian finite element-based model is presented. The key components of the model are highlighted and the force prediction capability of the model is validated against a substantial amount of engineering data. Good correlations between the prediction and the experiments were observed and some areas of further improvements for the model were identified.
