ABSTRACT:
An apparatus and method for grinding a workpiece by rotating the workpiece about a rotational axis, rotating a cylindrical grinding wheel about a rotational axis being parallel to the rotational axis of the workpiece, moving the grinding wheel relative to the workpiece at least in one of a first direction being perpendicular to the rotational axis of the workpiece for grinding the workpiece at a cylindrical surface of the grinding wheel and a second direction being parallel to the rotational axis of the workpiece for grinding the workpiece at an end surface of the grinding wheel being perpendicular to the rotational axis of the grinding wheel, and by superimposing a vibration signal including a plurality of frequency components to a driving signal outputted to one of a workpiece rotating means for rotating the workpiece and a grinding wheel rotating means for rotating the grinding wheel.
