摘要
A method of dressing a barrel worm-shaped tool to carry out the dressing of a barrel worm-shaped tool formed to grind tooth face of an internal gear with precision, dressing apparatus, and internal-gear grinding machine are provided. For this purpose, a disc-shaped disc dresser (13) is made to mesh with a barrel worm-shaped grinding wheel (12) having its diameter gradually increasing from the two end portions in the axial direction thereof towards the middle portion thereof and used to grind an internal gear (11). The barrel worm-shaped grinding wheel (12) is made to rotate around a tool-rotating shaft (B) disposed at a predetermined shaft angle (Al) with a vertical work-rotating shaft (CI) for the internal gear (11). The disc dresser (13) is made to rotate around a dresser-rotating shaft (D), the disc dresser (13) being disposed at an angle that is equal to a helix angle of the internal gear (11). While the barrel worm-shaped grinding wheel (12) and the disc dresser (13) mesh with each other and are rotating, the barrel worm-shaped grinding wheel (12) and the disc dresser (13) are made to revolve relative to each other within a horizontal plane.
