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.

A method for producing vehicle wheels, the method comprising:
- fixing a wheel body to prevent the wheel body from rotating around a rotation axis while a cutting edge of a cutting tool is in contact with a three-dimensional shape surface of a design surface of the wheel body;
- and
- three-dimensionally and continuously moving the cutting tool 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,
- wherein the cutting tool causes a specular glossy surface to be formed in the three-dimensional shape surface,
- wherein moving the cutting tool causes the specular glossy surface to be finished into a processed surface having a high metallic gloss property by exposing base metal of the wheel body from a coating layer previously disposed on the wheel body,
- wherein the specular glossy surface has a regular reflectance of 68% or more at an incident angle of 60°, and
- wherein an average height of processed grooves in the processed surface is not more than 1 μm.
