Abstract	Reducing the cost of manufacturing products can be realized by high performance, precise and productive machine tools. This goal is often obtained by the user increasing the adjustable machine parameters, which include the feed rate or the cut depth. Both will increase the grinding force during the grinding process, which can result in an excitation of the machine structure. If the excitation is too high, the machine structure can show an undesired dynamic behavior, which can cause the machine to vibrate. These vibrations can result in chatter marks on the work piece surface and if large enough can result in a production stop. One possibility to minimize the chance of excessive vibration is a conservative choice of machine parameters which are well below the optimal set for a particular machine. This paper presents an approach which shows the first results of an active tool holding device aimed at reducing unwanted vibrations resulting from an aggressive parameter choice.
