METHOD OF OBTAINING SURFACES WITH ALTERNATIVE PROJECTIONS AND HOLLOWS (VARIANTS) AND TOOL FOR ITS REALIZATION Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: method allows to obtain a relief in the shape of alternating ribs, pins, cells and projections of the triangular profile on the blank surface. The geometric parameters of the tool and the processing conditions allow to obtain the desired pitch, height and slope of projections. The tool sharpening is exercised in three planes. EFFECT: enhanced efficiency of the mechanical working of mechanisms in power engineering, chemical and cryogenic mechanical engineering. 19 cl, 5 dwg
