Abstract

There are many different reasons to use a model in the cutting and forming operations fields, such as the following: processes design, processes optimization, processes control, processes simulation, and equipment design. This chapter describes how the features to build a good simulative and analytical model. In order to realize a reliable simulative and/or analytical model for cutting and forming environments, it is important to know some parameters since they strongly influence the final results. The most significant parameters are material characterization (known also as flow stress law); friction model and value; and failure criteria of the material. In manufacturing processes, the knowledge of the friction conditions between a workpiece and a tool or die is very important for determining the material flow and the part feasibility. In order to quantitatively express the interface friction, it is normal to refer to two models: the Coulomb model and the Schley model.
