At IPH, interdisciplinary topics are worked on within the framework of various research and industrial projects. We offer you the opportunity to actively participate in these projects and to gain practical experience already during your studies.

Cross wedge rolling is a process from the field of solid forming. In the Collaborative Research Center 1153 "Tailored Forming", load-adapted, hybrid (i.e. consisting of several materials) solid components are produced and investigated. Process monitoring and control are becoming increasingly important in this context.

In order to develop an initial concept for process control, process control measures are to be determined and investigated simulatively (using FEM).

Your tasks

The determined input parameters, which lead to defects, are already known to a large extent and are reproduced in the simulation. Possible defects include necking, internal cavities (Mannesmann effect), skew, curvature, slippage and high stresses in the joining zone. For example, partially low friction leads to skewing of the semi-finished product.

The process control measures are to be determined for two types of shafts. For different defects and the determined causes from FP2 (e.g. rolling speed, temperature profile, tool parameters, friction) the influence of the measures to compensate the causes will be determined. For this purpose, the process parameters which were determined to be related to the defect will be varied systematically and inline.

Your profile

You are studying one of the following subjects:

  • Mechanical Engineering
  • Mechatronics
  • Industrial Engineering
  • or similar

You are interested in forming technology, materials and the determination of complex interrelationships. Previous knowledge in FEM is not necessary. The development of the necessary FEM knowledge takes place in the context of the master thesis.

Good written and spoken German and English skills are required.

We offer

  • independent work
  • flexible working hours
  • well-equipped workplaces
  • practical work activities
  • possibly long-term cooperation
