INVESTIGATION OF THE WEAR PROCESS OF DIAMOND GRAINS DURING CUTTING OF DIFFERENT MATERIALS

Abstract

The processes of cutting concrete, reinforced concrete and composite materials are investigated. The basic concepts of materials destruction processes when cutting with a diamond cutting wheel are considered. Loads on the diamond cutting wheel, providing the maximum performance in cutting concrete, reinforced concrete and composite materials, are determined. The wear mechanisms of the diamond grains with the same loads on the diamond grains when cutting different materials are investigated, which allows to state about cardinally different mechanisms appearing in the cutting zone.
