<P>PROBLEM TO BE SOLVED: To provide a method for dressing a threaded grinding wheel for grinding an internal gear, capable of accurately dressing the threaded grinding wheel for grinding the internal gear by using an accurately manufactured dressing gear. <P>SOLUTION: In a state in which a barrel-shaped threaded grinding wheel 11, which is disposed at an axial angle Σ to the internal gear W given at the time of grinding the internal gear W, and an external tooth type dressing gear 13, which is capable of meshing with a virtual external gear 14 virtually supposed so as to mesh with the internal gear W in place of the threaded grinding wheel 11 disposed at this axial angle Σ, have been meshed with each other, these threaded grinding wheel 11 and the dressing gear 13 are relatively moved in a circular arc in an X-Y plane, while being synchronously rotated, thereby allowing the dressing gear 13 to dress over an entire range of a grinding wheel axial direction of the threaded grinding wheel 11. <P>COPYRIGHT: (C)2012,JPO&INPIT |
