Abstract. The analysis of parts’ placement and orientation influence during punching process on the treated pieces quality was performed by analyzing practically the parts’ – fixing element’s layout, cutting, and bending processes. The possibilities to improve the performance of punching process and treated pieces quality by analysis of tools vibrations influence were theoretically performed there too.

Keywords: bending, calibrating, rolling, punching, punching force, vibrations.
