    Abstract: A cutter head for a mining machine includes a first end and a second end with a drum axis extending between the first and the second ends. The cutter head also includes a web coupled to the second end of the drum. The web includes a plurality of arcuate apertures. Each arcuate aperture extends through an angle about the drum axis. The cutter head further includes a plurality of first ribs coupled to the web. Each of the first ribs is positioned between adjacent arcuate apertures. The cutter head also includes a plurality of second ribs coupled to the web. Each of the second ribs extend across one of the plurality of arcuate apertures. A first angle that extends between one of the first ribs and an adjacent one of the second ribs is different than a second angle extending between the one first rib and another adjacent second rib.

    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.
