Selective wear of cuttings elements of working organs of tillage machines with realization of self-sharpening effect


The clause of strengthening of cuttings elements is conditioning and realization of such selforganization process as a self-sharpening. Sharpening of horizontal and vertical cuttings elements of working organs of tillage machines (CE WOTM) is considered in many works, but not found out the terms of realization and nature of these processes in a sufficient measure. The processes of sharpening and blunting of CE WOTM are related mainly to the processes of wear. The change of type of CE in the process of wear is conditioned mainly a size and character of tearing down each of its bevel and by volume of destruction of cutting edge in the process of exploitation in the medium of soil and depends on character of co-operation in tribosystem " WOTM -soil"
