The significance of contact friction in metal forming processes is very known. The general approach in this area involves the recognition of the influence of the main tribological parameters - pressure, speed and temperature in metal forming. The developed methods are very different for physical modeling of tribological phenomena and influence in a very specific types of metal forming. These methods basically have the appropriate physical model, which imitates local area or a complete work piece in metal forming. The indicators of models can be very different: the deformation forces, forming limit parameters distribution of stress, strain or temperature, etc. This paper analyzes the physical models in different metal forming processes, according to their characteristics and limitations.
