Abstract
A method is disclosed for detecting the wear of a cutter in a key-duplicating machine, the cutter being provided with cutting sections to obtain bitting cuts on a key and being put in rotation by an electric motor. The method includes measuring, during at least one cutting cycle carried out by means of the cutter, the values of current and/or voltage absorbed/required by the motor for rotation of cutter and/or motor torque values exerted by the motor. The values thus detected are used to determine if there is wear of the cutting portions of the cutter and/or to quantify the wear of the cutting portions of the cutter.
