Machinability study of particle reinforced aluminium metal matrix composites
In this thesis, machinability of particle-reinforced aluminium metal matrix composites, Comral-85 and DURALCANTM, has been studied. Continuous turning of round composite bars, using polycrystalline diamond (PCD) inserts has been selected as the test method. The test conditions included cutting …

Mechanische und elektronenmikroskopische Untersuchungen zum Verschleiß von Implantatbettaufbereitungsinstrumenten
Bisher gibt es keine wissenschaftlichen Studien, die den Verschleiß oder die Abnutzung von Spiralbohrern untersuchen, welche für die Bohrung eines kongruenten Implantatlagers benutzt werden. In der vorliegenden Arbeit wurde durch eine neue Methode versucht, die Schärfe der Implantatbohrer indirekt …

Integrated dynamical models of down-the-hole percussive drilling
… the activation modeled as a periodic impulsive force. The second and third models account for the dynamics of the piston and the activation results from the impact of the piston on the bit. They are respectively based on elastic and rigid representations of the two bodies. In the rigid model, …
