Abstract

The first results of different new sheet-bulk forming methods are presented in the article. It is shown how an additional superimposing of oscillation can be attached to the forming punch in order to improve the forming limit of the sheet material. New coating and atmospheric plasma-nitriding methods for processing of the forming tools (for improving of hardness and wear resistance) are also represented in the article.
