    Abstract: PROBLEM TO BE SOLVED: To perform highly accurate machining even if a parameter required for machining a gear by skiving is changed by suppressing an influence of the change on a cutter tooth surface shape.SOLUTION: A gear machining apparatus includes a skiving mechanism positioning a workpiece to be machined and a pinion type cutter 3 on axes displaced from each other, and manufacturing the gear from the workpiece by feeding the cutter 3 while rotating in a direction of a tooth trace of a gear to be formed at the workpiece synchronously to the rotation of the workpiece. The cutter 3 includes a tooth surface which is formed with an involute region 12 for forming an involute face 10P having an involute curve in an area including a pitch circle 11 in a tooth depth direction, an addendum region 13 continuously formed from the involute region 12 toward an addendum, and a dedendum region 14 continuously formed from the involute region 12 toward a dedendum, the addendum region and the dedendum region shaped in a configuration different from the involute region 12.
