Abstract
Disclosed is a method for dressing a threaded grinding stone for internal gear grinding, by which a threaded grinding stone for grinding an internal gear can be dressed with a high degree of accuracy by using a dressing gear that has been produced with a high degree of accuracy. In a state in which a barrel-shaped threaded grinding stone (), which is disposed at an axial angle (Σ) to the internal gear (W) that is conferred during the grinding of said internal gear (W), and an external tooth-type dressing gear (), which is capable of meshing with a virtual external gear () virtually formed in a manner so as to mesh with the internal gear (W) in place of the threaded grinding stone () disposed at the axial angle (Σ), have been meshed together, the threaded grinding stone () and the dressing gear () are simultaneously rotated while being moved relatively in a circular arc in the X-Y plane, whereby the dressing gear () dresses along the entire area in the axis direction of the threaded grinding stone ().
