The challenge of producing high performance, productive and precise machine tools must be accepted by the machine tool industry. These requirements can be reached by increasing the grinding machine parameters, such as the cut depth or the feed rate. Both will increase the grinding force during the grinding process, and can result in an excitation of the machine structure. Based on this excitation, the machine structure shows an undesired dynamic behavior which can result in machine vibrations. These vibrations can cause chatter marks on the workpiece surface, and if large enough can result in a stop in production. To minimize the chance of this situation, the machine user often chooses machine parameters which will not excite the machine structure. This is a disadvantage, because the machine design allows much more efficiency. To employ the complete efficiency of the design, this paper presents an approach which allows the active reduction of possible vibrations during a grinding process.
