摘要
The present invention relates to the use of an impurity doped first diamond layer of polycrystalline diamond disposed on a metal surface of a cutting tool for detecting the degree of wear of an undoped polycrystalline second diamond layer disposed on the doped diamond layer and which is a functional area of the cutting tool wherein at least one physical parameter is detected continuously or periodically during operation of the tool, and wherein a change in the parameter indicates the degree of wear of the undoped second diamond layer. As a result, the doped diamond layer forms a kind of "intelligent stop layer" for the tool, because changing the transition from the undoped to the doped layer, for example, the conductivity of the system changes and this change can be exploited to form a stop signal for the machine drive, before the Tool and the machined workpiece is damaged.
