An active tool holding device

The machine tool industry has to overcome many challenges to produce efficient, high performance and precise machine tools. These requirements are directly from the customers, who want the ability to produce more cost-effective. In order to achieve this, the machine parameters such as the feed rate or the depth of cut of grinding machines are increased. These new parameters affect the dynamic behavior of the machine tool, and in some cases can result in extreme vibrations. These vibrations can generate chatter marks on the workpiece surface or limit the ability to obtain a stable process. This article deals with an active approach to reduce possible vibrations within machine tools. Here the tool holding device of a surface grinding machine has been extended to create an active tool holding device. The active design allows the manipulation of the dynamic behavior of a surface grinding machine, allowing the implementation of a better parameter set.
