Digital Production

About TC Parsberg / Lupburg

The Technology Campus Parsberg / Lupburg is operated jointly with the OTH Regensburg. At the inter-university research location, skills in the field of "modern materials and their processing in digitalised production environments" are bundled. Here, research, teaching and training is carried out in five laboratories, numerous training rooms, a workshop and offices for up to 40 employees in an area of 2000 square metres.

Organigram

(in German)

 

A management committee was set up to manage the inter-university Technology Campus. The scientific management is carried out by three professors. One professor from the Deggendorf Institute of Technology, Prof Dr Andrey Prihodovsky, and three OTH professors, Prof Dr Stefan Hierl, Prof Dr Ulf Noster and Prof Tobias Laumer. Anton Schmailzl is responsible for the operative management.

As can be seen from the organisation chart, 28 people are currently working at the Technology Transfer Centre; this includes one vacant position among the scientific staff. Taking into account part-time contracts, the current full-time equivalent (FTE) is 20.5.


Main Areas of Research

DIT pursues the following research priorities at the Technology Campus Parsberg / Lupburg (Illustration in German):

Virtualisation: e.g. Computer-aided manufacturing (CAM) of virtual machines and additive construction processes

Process and Material Simulation: e.g. Simulation of welding processes, additive manufacturing and forming processes

Process Development and Optimisation: Focus on Hybrid Processing Chains, e.g. Laser deposition welding and milling

The focus is on both long-term research projects and short-term service and contract research projects. In detail the following is carried out:

  • Research projects with companies, institutes and universities, often with public funding
  • Contract research for companies in the district of Neumarkt, in particular for small and medium-sized enterprises (SMEs) and start-ups
  • Consulting for innovation projects

Projects

Equipment at TC Parsberg / Lupburg

At the TC Parsberg / Lupburg, which spans several universities, equipment is available in the following areas:

  • Material analysis (micro- and macroscopes, photo documentation workstation, automatic hardness testing equipment, vibration test bench, metallography, tensile-compression testing equipment, workstations for residual stress measurement)
  • Laser material processing (four laser protection cabins with corresponding safety technology)
  • Additive manufacturing (several plastic 3D printers)
  • Mechanical manufacturing processes (CNC lathe, pillar drilling machine, belt grinder, band saw, CNC milling machine)

In addition to the equipment, various software products are also available, which in particular enable the simulative mapping of manufacturing processes (CAD/CAM/PLM programmes, FEM programmes, etc.).

During the production of components in aluminium die casting, strong changes in temperature occur on the tool surfaces within a short period of time - so-called thermal shocks. Due to the thermal expansion, these cause mechanical stresses that lead to cracks and thus reduce the service life of the tools. Numerical simulation offers the possibility to test new concepts to improve the behaviour of the tools during thermal shocks.

Activities:

  • Development of a simulation model to calculate the mechanical stresses caused by thermal shocks in die casting tools
  • Simulation-based determination of the effects that cause stresses and analysis of improvement potentials
  • Development of concepts to improve tool life time
  • Implementation of the new concepts in the simulation model and execution of simulations
  • Evaluations of the new concepts by comparison with conventional tools.

The components to be analysed were manufactured using various DED processes (laser metal deposition, wire arc additive manufacturing and cold gas spraying). The properties of the components are subsequently compared with available simulation results and serve to validate these results.

Activities:

  • Analysing the chemical composition
  • Measuring and analysing hardness curves
  • Preparation of microsections and microstructural images
  • Carrying out adhesion tests
  • Carrying out heat treatments
  • Carrying out tensile tests
  • Evaluating and documenting all results
  • Programmes: MATLAB, SpArcfire

All experimental work must be carried out at the Technology Campus Parsberg-Lupburg and is only possible in presence.

The production of metallic thin films is of grear technological importance of microelectronics and related fields. Thin films of copper serve as interconnect material in current printed circuit boards due to their low electrical resistance, low specific weight, low production cost and ease of fabrication. Thin-film materials can be adapted to the required demands of the respective application by adjusting their properties during processing. Grain morphology, texture and stress are important aspects of the thin film properties. In the present work, the primary aim is to investigate influencing conditions for thin-film deposition and the surface properties of the substrates in order to improve the adhesive strength between different materials and to avoid detachment. The higher the adhesion strength, the longer the lifetime of the device to counteract premature delamination under both higher loads and contact pressures and to assess the overall reliability of the system.

Activities:

  • Fabrication of multilayer thin film structures of atmospheric plasma CVD thin film deposition
  • Structural and chemical investigations by scanning electron microscopy and EDC
  • Adhesion measurement of metallic thin films by pull method
  • State of the art of copper-ceramic plasme CVD thin film deposition systems

Laser powder cladding (LMD) and wire arc additive manufacturing (WAAM) are established processes in additive manufacturing with metals. These processes are based on the fact that the desired component geometries are built up by superimposing a large number of weld seams.

For a resource-efficient development of suitable machining strategies, these manufacturing processes are mapped and investigated in numerical simulation models based on the finite element method. Since the production of a component often requires weld seams several metres long, this results in very long calculation times, which is why the use of simulation in process design is currently little used. In order to make use of the advantages of numerical simulation in the design of LMD and WAAM processes, it is of interest to reduce the calculation time without causing a significant loss of accuracy in the calculation results. In order to achieve this, for symmetrical components it is possible to investigate the build-up process on a quarter or half model and thus simplify the calculation. Since only a fraction of the component is modelled, the boundary conditions have to be adapted accordingly.

It is to be tested how the boundary conditions are to be adjusted with this new approach in order to avoid an impairment of the calculation results. Likewise, it is to be tested how large the resulting computation time savings are.

Activities:

  • Conceptual design of different components for the test calculations
  • Modelling of the structure of the components without simplifications and calculation of the process sequences as reference simulations
  • Development of a strategy for the adaptation of the boundary conditions with geometric simplification of the components
  • Modelling of the structure of the geometrically simplified components with adapted boundary conditions and execution of the thus simplified simulations
  • Evaluation of the approach with regard to calculation time reduction and accuracy of the calculation results by comparing the reference simulation and the simplified simulation.
