Abstract
In a method for guiding a cutting head in relation to a material, a position and a speed of the cutting head are set by means of a drive unit depending on a desired position value and a desired speed value established by an interpolator unit, a control signal for the drive unit is determined, a distance between the cutting head and the material is determined with a distance sensor, and a corresponding distance signal is provided. The distance signal is compared with a predetermined comparison distance to yield a distance-control signal, and the control signal for the drive unit is additionally determined dependent upon a distance-control signal. The comparison distance is subtracted from the distance signal and the difference is superimposed on the actual position signal, which is delayed by a first time period, wherefrom the distance-control signal is determined.
