Abstract: The invention relates to a method and a device for machining materials by milling and/or drilling, in particular for removing rock, concrete, minerals or coal, having a tool drum (10) in which a plurality of tool shafts (9) which bear machining tools (7) at their ends projecting from the tool drum (10) are mounted such that they can be driven in rotation. A drive element (12) for the tool shafts and the tool drum (13) can be rotated relative to each other, and the drum carrier can be moved relative to the material by using a movement device (6, 7). By means of a control device, the speed of the relative movement between tool carrier (2) and material and the rotational speed of the tool drum (10) can be varied. In order to avoid critical operating points, the device is assigned at least one measuring sensor (30) for measuring the natural translational vibration and/or at least one measuring sensor (32; 34) for determining the rotational vibrations of the tool drum (10), and the control device has at least one vibration analysis module, by means of which, in a vibration analysis, a vibration spectrum can be determined, and at least one controller module, by means of which drive parameters can be or are controlled as a function of the vibrations determined by the analysis module.
