Provided is a method for machining a component by removing material, in particular by removing chips, within a groove provided in the component, in which method: spatially resolved measurement data, which include information about faults, in particular cracks in the component, are provided, and machining of the component by removing material, in particular by removing chips, is performed by means of at least one machining tool mounted for movement in a motorized manner, in particular for translation and/or pivoting in a motorized manner, and is controlled in accordance with the provided measurement data preferably in an automated manner with respect to the positions on the component at which the at least one machining tool is brought into engagement with the component in order to remove material in the region of faults that are present.

A portable rail weld milling machine apparatus comprises a metal frame that incorporates a motor with a rotary carbide tool that is able to lock to a rail or rails for stability. The apparatus houses the required guides and motors to maneuver the tool on a plurality of axes with computer numerical control (CNC). The CNC programming is able to control the carbide tool such that the welded rail can be milled to proper profile on the entire running surface, including the top, the field side, and the gauge side of the ball of the rail.

Various embodiments include a structure for positioning a tool on an elongated recess of a workpiece, wherein the elongated recess extends along a first longitudinal axis and has end surfaces on two end faces. The structure may include a plate having a cutout extending along an axis; a centering device; and a clamping device fixedly connected to the plate and the centering device. The cutout, when the second longitudinal axis is aligned parallel to the first longitudinal axis, enframes the elongated recess. The centering device includes a centering jaw movable within the cutout along the second longitudinal axis and also movable into and out of the elongated recess. The clamping device, on the side of the plate facing the elongated recess, includes clamping jaws movable along the second longitudinal axis to come into mechanical contact with one of the end surfaces of the end faces of the elongated recess.
