METHOD FOR SHAPING TOOTHED PROFILE PARTS Russian patent published in 2003 - IPC

FIELD: metal shaping technique, namely gear wheel shaping. SUBSTANCE: method comprises steps of working blank by means of grinding abrasive tool during several passes. In order to increase accuracy and to enhance quality of working due to stabilized thermodynamic action upon blank, cutting depth in each pass is selected according to condition that area of blank material removed in cross section of blank normal to translatory motion direction of tool relative to blank is constant at admissible fluctuation no more than 10%. Grinding abrasive tool may be dressed one and it may have profile copying that of recess. EFFECT: enhanced quality of parts with toothed profile. 3 cl, 4 dwg, 2 tbl
