Laboratory exercises
1. Semester
- Foundations of forming technology
- Strain hardening
- Deep-drawing, bending, cutting, impact extrusion
6. Semester (Practical application module metal forming/laser machining):
- Simulation with AutoForm: Tutorials developed at Esslingen University of Applied Sciences to accompany the lectures on metal forming help you to learn how to operate the AutoForm FE program using concrete, real-life applications.
- Rapid Prototyping: You develop the optimum size of the starting blank for a deep-drawn part. Every student produces a drawn part with the aid of a prototype tool cast from a low-melting point zinc alloy.
- Press drives: Different press drives are compared in the Metal Forming Laboratory.
- Laser technology: Learn how a laser can be used for machining materials.
- Programming of laser cutting and bending systems: At Trumpf (Ditzingen), you will develop a 3D shaped sheet metal part and program the laser cutting and bending machine for this part. The component you have developed will then be fabricated.
Master RMM:
- Efficient drives for metal forming presses: You gain direct experience of the advantages of the direct drive with a modern mechanical press with servo-drive.
- Method development: With the aid of concrete case studies, you develop the process chains to produce shaped sheet metal parts. You use the AutoForm FE system to support you.
Research and knowledge transfer
Research activities
The Metal Forming and Machining of Lasermaterial Laboratory headed by Prof. Dr. Wagner collaborates closely with industrial companies in Baden-Württemberg. Medium-sized and small companies are often looking for support with process engineering issues. They in particular require simple and low-cost solutions.
Here are several projects by way of example which are being undertaken in the Metal Forming and Laser Technology Laboratory:
Research activities and projects
- Resource efficiency along the sheet metal forming process chain
- Construction of prototype moulds from laser-joined metal sheets
- Development of a testing device for cutting oils
- Backspring during stamping of flat sheet metal parts
- Reduction in the number of forming stages with roll hemming
