Abstract
In a gear skiving process method, a tooth-cutting process is performed on a surface to be cut of a workpiece using a first skiving cutter disposed at a first processing position on the surface to be cut and a second skiving cutter disposed at a second processing position set apart by 180° in a circumferential direction from the first processing position. Parts that are to be right tooth flanks of internal teeth to be created in the surface to be cut of the workpiece are cut mainly by the first skiving cutter. Additionally, parts that are to be left tooth flanks are cut mainly by the second skiving cutter. Conditions of the processing performed using the first and second skiving cutters can be controlled individually and teeth having a shape in which the left and right tooth flanks are different can be processed efficiently.
