Abstract
There is proposed a method for examining the clamping state of a tool holder or tool which is clamped in a tool clamping device of a rotor unit of a motor-driven machine tool unit, with the spacing of the sensor head from a component of the rotor unit being measured, with a recording of at least one time and/or position-related sequence of the spacing values measured with the sensor head, wherein for improved integration of the method the recording of a first and a second time and/or position-related sequence is carried out during an acceleration of the rotation of the rotor unit with respect to the stator unit, in particular when the rotor unit is started up, wherein the time and/or position-related information of the sequence vectors of the first and/or second sequence is scaled using the respective associated current speed (v0).
