摘要：A tool is brought into contact with a radially outer part of an inner wall surfaceof a scrollwall along an X-axis at a position displaced from the center of a basic circle ofan involute curve by a radius of the basic circle along a Y-axis. Thereafter, the tool and thescrollwall are relatively moved along the X- and Y-axes while rotating the scrollwallabout the center of the basic circle and keeping a normal direction of the wall surface ata contact point with the tool parallel with the X- axis, so that the tool is brought intocontact with the wall surface from the same wall surface. In this way, the inner wallsurface, the wall surface at the center and the outer wall surface can be continuouslyprocessed in the same direction. The processing can be easily corrected based on aprocessing error resulting from the deviation of the positional relationship from apredetermined one, with the result that the processing accuracy can be maintained at asatisfactory level.
