摘要： A disk dresser and a dressing method enable high-precision dressing of a drum-shaped gear-like grindstone and shaping of the cutting teeth of the grindstone without changing the shape of the cutting teeth of the disk dresser. A drum-shaped gear-like grindstone is brought into linear contact with a workpiece so as to link with the contours of the tooth right angle cross-section orthogonal to the twist direction of the workpiece teeth. The grindstone and a disk dresser, in an engaged state, are caused to rotate synchronously, thereby causing the drum-shaped grindstone to be dressed by the disk dresser. The disk dresser blade shape is made to match the tooth right angle cross-section shape of the teeth of the ground workpiece. The grindstone and the disk dresser are caused to move and revolve in accordance with the drum shape and the angle of twist of the grindstone.

摘要： A method is disclosed for dressing a tool used for machining an internally toothed gear. The method includes meshing an internally toothed gear-like dressing gear, which is rotatable about the dressing gear rotation axis, with a barrel-shaped, screw-like grindstone. For machining an internally toothed gear, the outer diameter of the screw-like grindstone after dressing is estimated before dressing, the angle of intersection between a dressing gear rotation axis and the screw-like tool rotation axis is set on the basis of the estimated outer diameter of the screw-like grindstone after dressing, and dressing is performed with the dressing gear and the screw-like grindstone meshed with each other at the set angle of intersection between the axes.
