High-chromium cast irons are used as abrasion resistant materials. Their wear resistance depends on quantity of carbides and the matrix supporting these carbides. The paper presents the results of cast irons of chemical composition (in wt. %) 19–22 Cr and 2–4.5 C alloyed by 1.7 Mo + 5 Ni + 2 Mn to improve their toughness, which were tested in working conditions of ferroalloys crushing. The paper also examines the machinability of surface grinding, where the tangential and radial component of the cutting forces are the function of the cutting elements as the output characteristic of the process. The elements of the cutting regime were the cutting depth, the feed movement speed and the lateral shift. For modeling was used 3 factorial model plan of experimental design and neural network.
