摘要：
The article deals with problems of cutting process monitoring in real time. It is focused on tool wear by means of impedance layers applied on ceramic cutting inserts. In the experimental part the cutting process is monitored using electrical resistance measurement. The results are compared and verified using the monitored cutting temperature and tool wear. The testing of impedance layers is reasonable mainly for cutting edge diagnostics. The width of this layer determines the wear allowance of tool wear (flank wear). Excessive wear causes a sharp reduction of this layer and thus a sharp increase in electrical resistance, which is a warning signal of the end of the cutting edge durability.
