METHOD OF THERMODESTRUCTIVE WOOD CUTTING Russian patent published in 1998 - IPC

FIELD: cutting by a tool with cutting member heated by electric current. SUBSTANCE: in the process of wood cutting the values of tool forward force relative to wood are maintained within the preset deviations from the preset variation with the aid of an automatic control system with a closed feedback, in which variation of power of electric current heating the tool cutting member serves as control action. EFFECT: good quality of cut within a wide range of variation of forward force power in the process of cutting, including interruption of feed with subsequent continuation of cutting, enhanced safety for tool cutting member at maximum capacity limited by strength characteristics of tool cutting member. 2 cl, 4 dwg , 1 tbl
