Abstract: In a method for monitoring mechanical wear caused by a first component on a second component, wherein the first and second components are movable relative to one another and wherein the first and second component are at least at times in mechanical contact with one another, at least one sensor head is arranged in a wear area to be monitored of the second component. The at least one sensor head is mechanically worn by the first component upon reaching a predetermined wear limit. When the at least one sensor head is mechanically worn, a measuring signal is generated by the at least one sensor head or a change of a measuring signal, produced by the at least one sensor head prior to having been mechanically worn, is detected.
