    Energy efficiency in production is becoming increasingly important for the automotive industry, motivated by political regulations and competitiveness. Many theoretical approaches to achieve an efficient production via advanced control have only been tested in experimental environments. Important for the transfer into serial production is the proof that all requirements (e.g. quantity and quality) will be met. For ensuring production on demand, machine tools (MT) imitate the real production process to keep themselves at operating temperature. All subsystems of a MT operate at full power in this state, disregarding its necessity. Shutting down these subsystems during non-productive periods is a promising approach for saving energy. This paper will present a method for shutting down components during non-productive periods, while ensuring the ability to produce on demand. Successful tests were already performed during live operation in a plant of a car manufacturer in Berlin, Germany.

    Einsatzverhalten und Leistungsbedarfe unterschiedlicher Kühlungsmethoden beim Außen-Längs-Runddrehen
    (Fraunhofer Verlag, 2018)
    Fürstmann, Paul
    Die Drehbearbeitung hochwarmfester Legierungen stellt produzierende Unternehmen vor wirtschaftliche Herausforderungen. Insbesondere die physikalischen Grenzen verfügbarer Schneidstoff-Beschichtungssysteme limitieren die Schnittparameter und damit potenzielle Produktivitätssteigerungen. Eine wichtige Einflussgröße, welche den Prozesswirkungsgrad und die Produktivität beeinflusst, ist die Wahl einer geeigneten Werkzeugkühlung. Zum besseren Verständnis und mit dem Ziel die Produktivität trotz vorhandener Grenzen zu steigern, wird die Ursache-Wirkungskette des Werkzeugverschleißes bei der Trockenbearbeitung, der Trockenbearbeitung mit einem geschlossen-innengekühlten Drehwerkzeug mit Flüssigstickstoffkühlung und der Überflutungskühlung mit Kühlschmierstoff beim Außen-Längs-Runddrehen von TiAl6V4 analysiert. Ein weiterer Schwerpunkt dieser Arbeit ist die Modellierung der energetischen und wirtschaftlichen Effektivität und Ermittlung der jeweils günstigsten Prozessparameter. Aus den gewonnenen Erkenntnissen lassen sich zukünftige Entwicklungspotenziale ableiten, um die Fertigung hochwarmfester Werkstoffe energetisch effizienter und ökonomischer durchzuführen.

    This paper introduces and examines objectives and barriers that occur during the implementation of an energy management system (EnMS). It thereby presents the results of an empirical investigation regarding manufacturing enterprises in Germany conducted by the Fraunhofer Institute for Production Systems and Design Technology IPK. It further focuses on the context of German legislature and public facilitation made to promote energy efficiency. The results shall give recommendations where promotions made to energy efficiency should be aimed at and what potentials for improvement exist.
