    摘要: A method of producing, in a workpiece such as a spiral member of a scroll element, a curved groove for receiving a mechanical seal by using a milling cutter, especially, an end mill. A relative feed in a given direction "A" is provided between the milling cutter and the work, and the milling cutter rotating in a predetermined direction "B" about an axis of rotation thereof is set so that the milling cutter provides an inner side wall of the curved groove with respect to a center of curvature of the curved groove with an up milling in which the direction "B" is directed against the direction "A", and that the milling cutter provides an outer side wall of the curved groove confronting the inner side wall with a down milling in which the direction "B" is directed toward the direction "A", in order to suppress formation of coarse and rough surface on both the inner and outer side wall of the curved groove. Thus, the width of the curved groove can be constantly accurate over an entire length of the groove.
