Abstract
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.
