Popis:	Recently, attempts have been made to use 3D scanning to evaluate the wear process of working elements. This paper proposes a new approach to develop a wear model based on an in-depth analysis of changes in the shape of a working component of an agricultural machine. For this purpose, chisels of plowshares used under varied soil conditions were analyzed. Numerical models of worn-out working parts created using 3D scanning were the basis for developing the model. Based on the hypothesis of correlative dependence between changes in wear phenomena and the direction normal to the working surface, a new index was obtained: the shape degradation coefficient. The relationship between the shape degradation coefficient and changes in the profile of the working surface was examined to demonstrate the effectiveness of the application of the new wear model compared to field measurements. The results of work surface microstructure tests also confirm the accuracy of the wear presentation concept proposed in this paper.
