Abstract
A method and an apparatus are proposed for grinding cams having concave flanks on a camshaft, using a grinding wheel of relatively small diameter, which is used at least for finish-grinding. The axis of the grinding wheel runs at an angle to the camshaft longitudinal axis, and the grinding wheel is aligned at the same angle. In order to achieve a satisfactory running surface, the grinding wheel is tracked along an advance axis running perpendicular to the infeed axis, specifically as a function of the rotational position of the camshaft and of the positioning on the infeed axis.
