METHOD FOR ELECTRIC-CONTACT CUTTING OF METALLIC MATERIALS Russian patent published in 2002 - IPC

FIELD: processes and equipment for separating metallic materials. SUBSTANCE: method comprises steps of placing tool over product to be cut, feeding tool and driving it to rotation. Tool is fed with constant effort provided due to its gravity. Depending upon feed value of tool inclination angle of cutting line relative to horizon is determined according to given formula. Feed effort is determined in depending upon cutting rate, material properties, blank dimensions, working modes of process, size of disc electrode and so on. EFFECT: possibility for realizing method in field condition; reduced time period of cutting. 1 dwg
