How machine tools keep a cool head

Inhomogeneous and changing temperature distributions in machine tools lead to sometimes considerable quality problems in the manufacturing process. In addition, the switching on and off of aggregates, for example, leads to further fluctuations in the temperature field of machine tools. More than 100 specialists discussed these and other topics from the field of thermal research at the 1st Conference on Termal Issues in Machine Tools in Dresden from 22 to 23 March.
The results of the Collaborative Research Centre/Transregio 96 on the thermal-energetic design of machine tools formed a large part of the more than 40 technical papers. Researchers from Dresden, Chemnitz and Aachen are jointly developing models, components and overall measures to solve the conflict between energy consumption, accuracy and productivity.
Another highlight of the conference was the keynote address by Fraunhofer President Prof. Reimund Neugebauer. With forward-looking presentations and interesting examples on the topic of “Cognitive supported production systems – chances and drivers”, he drew attention to the emerging competition for production technology research in the areas of IT institutes.
At the end of the conference Prof. Steffen Ihlenfeldt gave an outlook on further research goals. The main initiator of the event and head of the department of cyber-physical production systems at the Fraunhofer IWU focused in his lecture on “Self-optimizing machine tools – a vision based on the digital twin”.
Afterwards, the conference participants were given practical insights into the previously discussed topics by means of live demonstrations in the test field of the TU Dresden.
The conference was initiated by the Institute of Machine Tools and Control Technology together with the European Society for Precision Engineering and Nanotechnology (euspen). The International Academy of Production Engineering (CIRP) supported the event. In future, the conference is to be continued at different locations in Europe every two years.
