Abstract
This paper describes on high accuracy contour grinding. Variation in normal grinding force affects on the machining accuracy in contour grinding using a machining center because of grinding wheel with low stiffness. It is necessary in order to achieve higher efficiency and accuracy contour grinding to minimize the variation of the normal grinding force. Some methods has been tried to improve machining accuracy. However, influences of the normal force due to dynamic pressure caused by coolant flowing into grinding point has not been considered. Therefore, the normal force variation was estimated in consideration of contact arc length in order to improve machining accuracy. As a result, the variation of normal grinding force could be reduced in contour grinding.
