Energy-Efficient Product and Process Innovations in Production Engineering
CIRP Research Group

CIRP Research Group

The International Academy for Production Engineering (Collège International pour la Recherche en Productique (CIRP)) is the world's leading organisation in the field of production engineering research. The CIRP was founded in 1951 with the goal of answering scientific questions in the field of modern production science and engineering, by means of international collaboration.

With the support of the CIRP, an interdisciplinary, international research group has been set up, which is contributing considerably to the global visibility and recognition of the cluster. The scientists involved in the various fields of action are grappling with fundamental theoretical problems associated with the analysis, modelling, classification and explanation of energy-related processes, phenomena and physical laws in production. Matters of interest include questions arising from the interaction of product development, product manufacturing process chains, materials and structural designs, as well as from the planning of production, logistics and factory systems, and their control in energy-efficient factory operation. The group has initiated and supported work at the interfaces between the fields of action which has an interdisciplinary orientation.



Working Content of the CIRP Group

The focus was on fundamental theoretical problems associated with the analysis, modelling, classification and explanation of energy-related processes, phenomena and physical laws in production. Through empirical and experimental studies, theoretical approaches were to be developed, details specified and their significance for the planning and control of energy-efficient production demonstrated. The studies focussed on:

  • Energy conversion (efficiency of energy converters, shortened chains of effects)
  • Energy storage (capacity/time, recirculation, cycles)
  • Energy transport (heat losses, heat transfer, heat conduction)
  • Energy-efficient machining processes (machine-process interaction, energy-optimised massive forming, reduction of energy loss due to friction, simulation models, adjusted development methods, error compensation)

Introducing the Scientists

Dr.-Ing. Martin Kolouch, Czech Republic
Coordination of both organisational and technical aspects, as well as deadline and content-related agreements with regard to the CIRP group
Coordination included the moderation of discussions and voting procedures with the heads of the respective fields of action.
Dr.-Ing. Alwyn Bester, South Africa
Development of an alternative heating method for manganese-boron steels
The objective was the simultaneous temperature control and coating of the metal blanks for the press hardening process.
M.Sc. Ivan Dudarev, Russia
Development of a new method for the visualisation of energy flows on the basis of particle systems
Through the use of the various parameters of the particle system, energy flows can be dynamically and clearly visualised.
Dipl.-Ing. Anna Guk, Russia
Development of a material model for roll forming
To this end, a description of the cold pre-forming process and its influence on static softening in the event of subsequent heating was compiled. In addition, the influence of the heating process on the material behaviour during roll forming was determined.
M.Sc. Boudaima Idrissou, Togo
Increasing efficiency in massive forming, and loss minimisation
To this end, a detailed analysis of the process chain for tool production, workpiece manufacture and workpiece heating was performed, in order to identify areas of potential.
M.Sc. Giacomo Leopardi, Italy
Process parameters and interaction of materials for laser-assisted milling
Here the focus of the studies into laser-assisted milling (LAM) was on increasing the machinability of nickel-based superalloys that are difficult to machine.
Dr.-Ing. Enrique Meza-García, Mexico
Microstructural and mechanical characterisation of steel materials that can be press hardened
In addition, structural simulation of the transformation kinetics of these steel materials during the press hardening process was realised.
Dipl.-Ing. Iñaki Navarro, Spain
Development of self-adapting structures
The property changes in these structures are independently triggered as a result of the change in load. One specific approach was the use of the heat produced through friction in the main spindle system to regulate pre-stress.
Dipl.-Ing. Yury Shchus, Russia
Realisation of thermomechanical forming simulations
The studies to determine the influencing factors for the configuration of tailored component properties were carried out on the B-pillar base demonstrator tool. The focus was the calculation of the metal sheet cooling speed and phase components.
Ing. Flaviana Tagliaferri, Ph.D., Italy
Statistical analysis of process parameters using design of experiments (DoE)
The objective was the integration of statistical and technological knowledge. The focus was on processes such as laser-assisted milling, grinding and thermal laser treatment.
Dipl.-Ing. Bin Zhu, China
Reduction of friction in hydrodynamic sliding guides
The investigations into friction behaviour adopted various approaches such as the optimisation of the geometric design of guide surfaces, the application of DLC coatings and the microstructuring of the guide surfaces.
