Electromagnetic System to Improve the Manufacturing Accuracy at the Presence of Horizontal Process Forces

Forming asymmetric parts leads to horizontal process forces applied to the ram of a form-ing machine. These forces entail horizontal ram displacement and influence the quality of the pro-duced parts negatively. By application of horizontal counterforces to the ram, the displacement can be avoided and the process stability be improved. For the purpose of applying horizontal counter-forces, an electromagnetic system, which will be integrated in a forming machine, is currently under development. The requirements to the system are presented as well as the design optimised in vali-dated electromagnetic simulations and the approach for the mechanical integration into a forming machine.
