Abstract
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.
