Experimental and numerical analysis of chip formation in metal cutting
High speed cutting (HSC) is strongly discussed in modern production engineering. Many examples from industry show the advantages of this technology. However, the influence of high cutting speeds on machine tool, tool and workpiece quality have to be known. The current work describes the thermal and …

Abscheidung und Charakterisierung von PECVD-Aluminiumoxidschichten
Nowadays, thin films are used widely to increase the life-time of the tooling surfaces. Alumina coatings are known to exhibit advantageous mechanical properties as well as chemical inertness and oxidation resistance at high temperatures. Hence, this material is a suitable candidate for coatings …

Röntgenographische Bestimmung von Mikrospannungen in polykristallinenen Werkstoffen und ihr Verhalten bei statischer Verformung und schwingender Beanspruchung
Residual stresses are mechanical stresses in components, which are free from outside forces, moments and temperature gradients. They can considerably influence failure limits since they overimpose with external stresses. Two categories of residual stresses are macro residual stresses and micro …

Bestimmung des Formänderungsvermögens bei der Kaltmassivumformung
Up to now there is no quantitative prediction of the workpiece material deformability in cold forming processes possible. Using the current fracture criteria the moment of a crack initiation is not predictable. Such a numeric determination of the deformability would afford an improved economic …

Thermische Analyse des Zerspanens metallischer Werkstoffe bei hohen Schnittgeschwindigkeiten
The temperatures occuring in a machining operation affect the whole process, since parameters as tool wear, material behaviour and friction are influenced. A turning process with cutting speeds up to 100 m/s is investigated in this work for the workpiece materials AISI 1045 steel, AA 7075 …
