Abstract
The step being performed in a state where a wheel body is fixed to be prevented from rotating around a rotation axis while a cutting edge of a cutting tool is in contact with the three-dimensional shape surface of the design surface in the wheel body, the cutting tool being three-dimensionally and continuously moved relatively along the three-dimensional shape surface while being changed in direction with respect to the three-dimensional shape surface to allow a rake face of the cutting tool to face a tool travel direction to perform three-dimensional continuous cutting processing that allows a specular glossy surface to be automatically formed in the three-dimensional shape surface, the specular glossy surface being finished into a processed surface having a high metallic gloss property by exposing the base metal.
