Thermomechanische Wechselwirkungen beim Zerspanen

Kurzfassung Aktuell existieren keine direkten und zuverlässigen Methoden für die Bestimmung der Gleitwiderstandskraft, welche die Reibungsbedingungen an den Kontaktoberflächen beim Zerspanen sicherstellen. Die größten Schwierigkeiten hierzu liegen in der Gewährleistung der chemisch-physikalischen Phänomene, die während des Zerspanens im Kontakt herrschen. Für die Modellierung der Wechselwirkungen im Kontakt wird sehr oft das Coulomb'sche Gesetz verwendet, ungeachtet der Nichtübereinstimmung der Prozesse in der Kontaktzone. Dies steht aber im Widerspruch zu den modernen Erkenntnissen über die wirkenden Reibungsprozesse im Werkzeug-Werkstück-Kontakt.
