Abstract
A method of grinding a curved corner portion of a workpiece by a grinding wheel having a curved edge surface whose radius is smaller than that of said curved corner portion. The grinding wheel is movable along a path extending at an acute angle to the axis of rotation of the workpiece. First, the grinding wheel is relatively moved to a first grinding start position. Then, the grinding wheel is moved inwardly to an advanced position along the path so as to perform a plunge grinding operation, and is subsequently retracted to the grinding start position. After that, the grinding wheel and the workpiece are relatively moved so as to move the grinding start position to the next grinding start position along a curved arc which is in parallel with the curved corner portion of the workpiece. The above plunge grinding operation is repeatedly performed from each grinding start position thereby grinding the curved corner position.
