Heat Treatment

Laser heat treatment is used to locally functionalize components and semi-finished products. To improve wear protection, companies use lasers to harden steels for e.g. tools and molds. The precise and local heat input helps minimize distortion. To locally improve the formability of, for example, work-hardened metal sheets, they commonly turn to ...

Influence of Stamping Tool Fixation on Vibrations Using ...

In sheet metal forming, the fixation of tools in presses has not been considered to be variable for process optimization yet. Every clamping point fixes the tool. Tool areas without a fixation point have a vertical degree of freedom, respectively. Against this background, it seems to be evident that the kind of tool fixation can influence its static and dynamic beahviour.
