摘要

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 WOTMare related mainly to the processes of wear. The change of type of CE in the process of wear is conditionedmainly a size and character of tearing down each of its bevel and by volume of destruction of cutting edge inthe process of exploitation in the medium of soil and depends on character of co-operation in tribosystem "WOTM -soil".
