Method for monitoring the condition of a hard finishing machine, in particular a grinding machine

A method for monitoring the condition of a hard finishing machine, in particular a grinding machine, wherein the hard finishing machine has a number of NC-controlled axes which are actuated during the machining of a workpiece, wherein, for the purpose of evaluating the condition of the hard finishing machine, at least one reference run is performed on at least one axis, during which a response of the axis to a drive signal is measured and evaluated, wherein the reference run includes a phase in which the axis is accelerated and/or braked, wherein for the assessment of the wear condition of the hard finishing machine the response of the axis to the drive signal is measured and the measured response is compared with expected signal curves, which were present when the axis was in proper condition, wherein a statement is derived from the comparison as to whether the axis is in a proper condition.
