Abstract
A method of processing a leading portion of a rotating workpiece is performed by rotating a tip mounted on a cutter shaft and facing an outer circumferential surface of the workpiece. The tip has a small radius of rotation for high precision processing with small cutting resistance. The leading portion is cut by the tip with the cutter shaft inclined to a side opposite to the leading portion of the workpiece with respect to a direction orthogonal to the axis of rotation of the workpiece.
