Basing on the analyses of the available constructions the principles of conjugate-asymmetric allocation of the cutters with the corrected plane angles in the boring tools, have been proposed. Dependencies for finding the cutter and revolution feeds, as well as the values of the plane corrected primary (for the first option) and secondary (for the second option) angles, depending on the parameter of the calculated height of the profile roughnesses, have been obtained for two options of their construction design. The option of the tool design according to the proposed principles has been presented. The testing of the tool on the turning lathe with special device and «tension scheme» operation has been carried out. The maximum feed for certain machining condition has been found experimentally. Its efficiency advantages in comparison with those of conventional ones have been described.

Key words:

boring tool, conjugate-asymmetric allocation, cutter, feed, plane primary angle, plane secondary angle, profile roughness size
