  • Patent number: 9347315
    Abstract: A method and device for machining materials includes a tool drum having tool shafts that support machining tools that can be driven in rotation. A drive element rotates the tool shafts and the tool drum relative to each other, and a drum carrier can be moved relative to the material by using a movement device. A control device varies the speed of the relative movement between the tool carrier and material and the rotational speed of the tool drum. To avoid critical operating points, one measuring sensor measures the natural translational vibration and/or another measuring sensor determines the rotational vibrations of the tool drum. The control device has a vibration analysis module, by which a vibration spectrum can be determined, and at least one controller module, by which drive parameters can be controlled as a function of the vibrations determined by the analysis module.
