WEAR MODELING OF CARBIDE TIP OF THE ROAD HARROW CUTTER

The wear of the cutting tool such as the carbide tips of the road harrow cutters is modeled. The theoretical basis for modeling was the theory of abrasive wear by J. Archard and the theory of cutting (milling). The model was verified based on the results of bench tests on a stand simulating the operation of a road harrow cutter drum. The tests were carried out on an asphalt-concrete mixture containing, Mikashevich 1400 granite as the main abrasive. The binding element was the organic binder BND 70/100. A comparison of the model calculation results and the test results showed minor differences on the friction path under consideration.
