Abstract

This article extends the series of articles focusing on introduction and testing the behaviour of impedance layer applied on cutting edge of the tool. This coating functions as a regular cutting tool coating, but also it creates an electric circuit. According to presumption of the Theory of Cutting this layer should wear out during the cutting, it means to cut down its intersection. Decreasing the intersection of the layer leads to change of impedance until the cut-off of electric conductor. The electric circuit will be disrupted. In this sense it is possible to evaluate achievement of wear out criteria of the cutting tool edge. The tools, which are able to report its wearing this way are called „intelligent tools“. This article will be analysed and evaluated behaviour of such impedance layer on exchangeable cutting edge made of cutting ceramics during cutting of X120Mn12 material.
