FIELD: turning. SUBSTANCE: method involves changing spindle rotational speed in inverse proportion relative to part radius; changing instantaneous feeding in direct proportion relative to spindle rotational speed; withdrawing tool in the direction perpendicular to current feeding direction, when power parameter reaches extreme value, on the basis of dependence providing constant power parameter and simultaneously changing instantaneous feeding in current direction on the basis of dependence providing required total value of instantaneous feeding. EFFECT: increased efficiency and improved quality of parts. 5 dwg
