Abstract
The article offers the force and geometry analysis of the stone block–diamond wire saw system. The friction force of the diamond wire saw in the block is determined at the parabolic adjustment of the wire sawing trajectory. The curves of the sawing force and horizontal coordinates of the blocks are plotted at different values of the parabola focus point. The actual sawing trajectories in monoliths and blocks are described. The load increase factor at the beginning of work is obtained. Using the procedure of the actual sawing trajectory, the strength analysis of the diamond segments of the diamond wire sawing machine is performed, and the stress diagrams in the diamond segments with a sharp and rounded edge are constructed. The maximal stresses in the diamond segment with the rounded edge are plotted as function of the rounding radius.
