The RG Simulation and Process Design focuses on the simulation-based analysis and optimisation of NC machining processes with defined and undefined cutting edges (Fig.).
Basic investigations, e.g. the machining of hardened high-speed steel, are complemented by the development of innovative processes for structuring freeform surfaces using milling and grinding processes as well as the analysis of additive and subtractive process chains.
In cooperation with the RG “Virtual Machining” at the Chair of Software Engineering, one of the main research topics is the development of process simulation systems for the analysis and optimisation of machining processes. Regarding for example the simultaneous multi-axis micro- and macromachining of complex structures, e.g. for the mould and die production or the aircraft industry, a simulation system for the analysis of the changing engagement conditions during the NC milling of complex free formed surfaces and the resulting effects is developed. For instance, the loads on the milling tool, complex vibration effects, thermomechanical deformations, and tool wear are investigated in various research works. The modelling and analysis of regenerative vibrations resulting from the interaction of the machining process and the dynamic behaviour of the tool-workpiece-machine-system is one of the main research areas. In addition to the milling simulation, models for grinding and honing are developed to predict the resulting surface topographies.
In conclusion, the potential of process simulations, whose application area comprises detailed analysis of the machining process at the cutting edge, the design of fixture systems and machine tool concepts, and the utilisation during the factory planning process, is investigated in different projects of fundamental research and industry-related cooperation.

Location & approach
Arrival by Deutsche Bahn to Dortmund or Bochum central station.
From Dortmund central station, take the S1 city train in the direction of Düsseldorf to the "Dortmund Universität" station (7 minutes journey time).
From Bochum central station, take the S1 city train in the direction of Dortmund to the "Dortmund Universität" station (14 minutes journey time).
The city train runs regularly every 20 minutes in both directions. From the city train station, take the Skytrain (S-Universität stop) to the Campus Süd stop (1 stop, runs every 10 minutes).
From Dortmund Airport
By taxi to TU Dortmund University, Campus South (approx. 20 min and 30 €, see Map)
From Düsseldorf Airport
Take the city train S1 in the direction of Dortmund to the "Dortmund-Universität" station (approx. 60 min). From here, take the Skytrain in the direction of Campus South or Eichlinghofen (runs every 10 minutes and takes approx. 3 min.).
The H-Bahn is one of the hallmarks of TU Dortmund University. There are two stations on North Campus. One (“Dortmund Universität S”) is directly located at the suburban train stop, which connects the university directly with the city of Dortmund and the rest of the Ruhr Area. Also from this station, there are connections to the “Technologiepark” and (via South Campus) Eichlinghofen. The other station is located at the dining hall at North Campus and offers a direct connection to South Campus every five minutes.
The facilities of TU Dortmund University are spread over two campuses, the larger Campus North and the smaller Campus South. Additionally, some areas of the university are located in the adjacent “Technologiepark”.
