Its functions are being constantly redefined as a result of the changing paradigm of communicating on the local level. Local government press gains particular importance during any election campaign becoming the carrier of information for local authorities seeking reelection. The following text presents the results of research carried out in selected cities with poviat rights in the last quarter of 2014, during the local government election campaign in Poland.展开更多

The goal is to avoid local thinning by strengthening the weak point using local hardening. BDD operations are realized before the conventional deep drawing process. This results in a local strain hardening at the weak point of the workpiece, which is usually located at the bottom punch radius. Two major aspects have to be given attention due to the high number of process parameters. On the one hand, for process design, it is helpful to have a tool by means of which it is possible to simultaneously create both the machine program for the servo press and the initial configuration for the process simulation.
