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.

摘要： A method for shaping a scroll member for a scroll compressor, capable of increasing a service life of a cutter tool, while reducing the cost. At the corner between the base plate 2 and a scroll wall, a roundness 3a of a small radius R1 of curvature is first machined along an entire length of the scroll wall in its spiral direction. Then, a roundness 3b of a large radius R2 of curvature is machined only at a spirally inner end of the scroll wall.

摘要： A method for machining a groove in a sealing member and the edges of the groove. A tool 24 is formed with a top portion 24 having cutter sections 23A, each defining a cutting edge 23 for machining a groove in a scroll wall of a scroll member, and a tapered part 25 having cutter sections 26A, each defining a cutting edge 26 for bevelling the edges of the groove and the edges of the scroll wall. The groove 9 and edges 11 are simultaneously machined.
