Abstract
A method for manufacturing a vehicle wheel of the present invention includes a step of performing an edge treatment including deburring of a spoke edge generated by lathe processing. For the edge treatment, a cutting tool as hale type tool for non-rotational processing is used, and the cutting tool is provided with a processing blade having a recessed blade edge having an R shape or polygonal C shape protruding from an outer peripheral surface on a side of a tip end of the rod-shaped cutting tool connected to a rod-shaped shank portion. A processing machine capable of CNC of four or more axes is used. With the cutting tool standing upright against a disc surface, the blade edge of the processing blade is applied to the spoke edge, and the cutting tool is continuously moved relative to the spoke edge along a ridgeline of the spoke edge for scraping.
