WAY OF FINISHING ABRASIVE MACHINING OF OUTER ELLIPTICAL SURFACES Russian patent published in 2003 - IPC

FIELD: machining of metals, grinding of parts with outer elliptical surfaces. SUBSTANCE: wheel embracing part and made component of individual abrasive segments forming peripheral inner cutting surface is used for grinding. Cutting surface is divided during dressing into two parts equal in height and placed at angle α with rotation axis of grinding wheel. The latter is set at angle α with longitudinal axis of part and is given longitudinal feed relative to immobile part and cross cutting-in feed by way of growth of angle α per each double stroke of longitudinal feed. Description has design formula to determine value of angle α depending on value of major and minor semi-axes of elliptical surface. EFFECT: expanded technological potential of way, enhanced precision and quality of machining. 2 cl, 2 dwg
