In many companies is the main technologists problem reduce of production costs. One of the many solutions this problematic is almost 100 % utilization tools durability. In companies that use serial line is not used full tool durability. They prefer change the insert previously that they risking worse than requesting surface quality or their total damage due to destruction cutting edge. For this reason is usually fixed cutting tool durability, after which is cutting edge change, if it is still able to cut with required quality of machined surface. This leads to increase non-productive times and to waste money for tools. There are many ways of cutting edge diagnostic that can detect wear of cutting edge during machining. None of these diagnostics method is not widely yet. The reason can be complexity evaluation, special requirements for using, high demands on technical equipment or high price. This paper deals with using of diagnostic methods for monitoring cutting edge wear by resistive layers on selected types of material. The method of cutting tool diagnosis by resistive layer has the potential for mass adoption. This diagnostic method is very suitable for unattended machining system, especially due to simplicity and ease of applicability for machine tools and opens wide possibilities.
