Toolbox for control system analysis of machine tools
(2012)Machine tools have to reach high levels in accuracy and speed. For the detailed analysis of the machine dynamics with respect to these properties, a machine model has to include the main concepts of multibody dynamics and feedback control systems. With such a model available, dynamic investigations in frequency-and time-domain can efficiently be done. This work shows how to build a multibody system, and its integration in the feedback ...Working Paper -

Evaluation of active structural vibration control strategies in milling process
(2012)The ability of different active control strategies to mitigate the apparition of structural oscillations, like forced and self-excited vibrations, of the tool center point during milling process are evaluated and compared using specific measures. These measures quantify the efficiency for vibration suppression by some strategies and the corresponding costs involved. The objective is to be able to identify and dimension the most appropriate ...Working Paper -
On-machine wire electrical discharge dressing (WEDD) of metal-bonded grinding wheels
(2012)Metal bonded diamond wheels, due to its strong grain retention and thermal conductivity properties are generally used for grinding difficult-to-cut materials, such as high performance ceramics. On the other hand, the poor dressability of this type of bond limits its application. This study aims to evaluate the use of a wire electrical discharge machining principle for truing and dressing metal bonded grinding wheels. Through the EDM ...Working Paper
