Metal Forming Technology and Laser Material Processing Laboratory (UTL)

Tasks

In the Metal Forming Technology and Laser Material Processing Laboratory, practical experiments to accompany the lectures on production engineering, metal forming and laser material processing are carried out in the form of laboratory exercises, project work is supported, and Bachelor and Master theses are supervised.

The tasks are supported with simulations and cover the whole process chain from the design of shaped sheet metal parts via the production through to the jointing.

  • Sheet metal forming: deep-drawing, bending, stretch forming, tribology, cutting
  • Bulk deformation impact extrusion, compression, rolling
  • Laser material processing: laser cutting, welding, marking
  • Press technology: structure, press drives
  • Tool engineering: method development, design, prototype dies

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

 

Industrial partners

  • Schuler AG, Göppingen
  • Trumpf GmbH & Co. KG, Ditzingen
  • AutoForm Engineering Deutschland GmbH
  • Daimler AG, Sindelfingen
  • Behr, Stuttgart
  • IgeL (Ingenieurgesellschaft für Leichtbau), Schönaich
