METHOD FOR AUTOMATIC COMPENSATION OF TENSION STRESSES DEVELOPED ON CUTTING PLATE FRONT SURFACE IN THE PROCESS OF CUTTING Russian patent published in 1995 - IPC

FIELD: tool-making. SUBSTANCE: method involves measuring displacement of zone proximate main cutting edge, with displacement value representing maximum tension stress acting on cutting plate front surface; correcting position of zone proximate main cutting edge on the base of data obtained by measurement so that compressive stress equal to maximum tension stress is developed on front surface of cutting plate. EFFECT: increased efficiency, simplified construction and enhanced reliability in operation. 1 dwg
