<p>Cutting insert for chip-removing machining comprising an upper face (11), a lower face (12) and, connecting those, edge surfaces (13). Lines of intersection between the edge surfaces and the upper face form cutting edges. The insert (10) has a substrate (14) comprising a metal and a photon-emitting material. The substrate (14) is covered by a photon-tight layer (15). During wear of the layer (15) the substrate (14) is exposed, and therefore the intensity and direction fo the photons can be detected for determination of the size and type of the wear damage.</p> |
