TL;DRAbstract
It is important – as shown in the preceding chapters – to be able to predict the deformations and the metal flow in metal forming with sufficient accuracy. The importance of knowing such factors as the pressure against the die and the required forming load was early recognized by the metal former. Much work was therefore done to develop theoretical models that could be used to predict these parameters, so that they could be estimated with sufficient accuracy before a new process was set up. The theoretical models established for this purpose showed that the forming load depended on such factors as die geometry and friction, for instance, and in hot forming also on the forming speed. With the development of theoretical methods, it also became possible to calculate the effect of each factor on the forming load.
