Practical laboratory exercises are offered to deepen and practically illustrate the lectures on metal forming technology and laser material processing in the Bachelor's and Master's degree programmes.

Fundemantals Metal Forming Technology

Learning the basic processes of sheet metal forming such as deep drawing, bending and cutting of sheets, as well as bulk forming like the processes of cold extrusion.

Deep Drawing

For a specific deep-drawn part, the optimal cutting of the initial blank is first derived. Using a prototype tool cast from a low-melting zinc alloy, each student produces a deep-drawn part.

In further deep-drawing tests, a model engine hood is produced (see picture).

FEM-Simulation

Accompanying the lecture on metal forming technology, students learn how to use the FE programme AutoForm with the support of tutorials developed at Esslingen University. The process chains for the production of sheet metal parts are developed on the basis of real case studies. Measurement of the positional uncertainty of a zero-point clamping system

The following pictures show examples of projects carried out in the Metal Forming and Laser Material Processing laboratory.
