The present work fulfills the analysis of dependences of cutting resistance force, total resistance force, angular
acceleration of driving pulley on various operating and constructive parameters of rope operating devices. Scientifically
proven rational operating and constructive parameters of rope operating device have been determined, which provide
their efficiency and capacity improvement, reduction of the prime cost of the process of stone cutting with minimum raw
material loss and minimum energy consumption. Projection has been made over the possibility of developing constructions
of rope operating device of a stone cutting machine. According to the results of the analysis of dependences of operational
and constructive parameters of rope operating device precise recommendations over the creation of advance designs
have been worked out. The results obtained can be used in stone milling and stone working branches of industry; they
can also be used by scientific-research institutes and experimental design bureaus, which design and create advance
designs of stone cutting machines with rope operating devices.

Key words: stone cutting machine; rope operating device; driving pulley; cutting diamond rope; cutting process; cutting force; feed force; resistance force; cutting speed; angular speed; coefficient of sliding friction; coefficient of resistance towards relative shear or cut; natural stone.
