Simulation of the tribological behaviour of components and cutting tools by means of model wear testing

Modelling the wear test process can initiate real-life friction and wear of components and cutting tools. In this paper we describe model wear tests that were developed to discover (a) whether or not simulation of the wear processes that occur during cutting is possible, and (b) how the wear of indexable inserts can be reduced by using thin hard coatings, e.g. TiN, (Ti,Al)N, Ti(C,N) when milling metallic materials. The real-life wear of the track groups of various tracked vehicles was also investigated, in order to evaluate the wear resistance of certain materials.
