METHOD FOR MATERIAL MACHINING BY CUTTING Russian patent published in 1998 - IPC

FIELD: machining; may be used for machining various conducting materials in mechanical engineering, in particular, turning and milling. SUBSTANCE: method consists in giving of shape-forming motions of feed and contact electric heating of cutoff layer. Zone of electric heating is located before the zone of chip formation. Heated section of machined part is equal to value of allowance for subsequent finishing operation, and feed value, on the contrary, is selected in excess of hardened layer of machined surface. EFFECT: higher efficiency. 1 dwg
