METHOD OF METAL WORKING BY MEANS OF CEMENTED-CARBIDE TIPPED TOOLS Russian patent published in 2003 - IPC

FIELD: mechanical engineering. SUBSTANCE: invention relates to cutting and shaping of surfaces of parts manufactured of structural and hard-to-machine materials. Proposed method includes preliminary regulated heated of tool cutting part with subsequent shaping f surface by cutting and maintaining corresponding temperature of tool cutting part. To decrease labor input and increased durability of cutting tool, first temperature of maximum serviceability is determined which corresponds to point of inflection between rising and second horizontal sections of impact strength coefficient-to-temperature curve. Tool cutting part is preliminarily heated to indicated maximum serviceability temperature and said temperature is automatically maintained by cutting at corresponding cutting conditions. EFFECT: improved quality of metal working. 1 ex, 3 dwg
