To provide a gear machining method which can lengthen a service life of a gear skiving cutter and shorten a machining time by reducing a difference in machining allowance between both tooth surfaces.SOLUTION: The gear machining method includes: a step (S13) of estimating a difference ΔV between a first reference value that is a correlation value of magnitude of thrust force of cutting force on a first tooth surface 71 constituting a protruding tooth 70 of a gear and a second reference value that is a correlation value of magnitude of thrust force of cutting force on a second tooth surface 72 constituting the protruding tooth 70, which is positioned on a back side of the first tooth surface 71; a step (S14) of determining a specification of a gear skiving cutter T in which the difference between the first reference value and the second reference value is within a predetermined range; and a step (S18) of machining a work-piece W using the gear skiving cutter T having the determined specification.SELECTED DRAWING: Figure 11 【課題】両歯面の取り代の差を小さくすることにより、ギヤスカイビングカッタの長寿命化および加工時間の短縮を図ることができる歯車加工方法を提供する。【解決手段】歯車の凸歯７０を構成する第一歯面７１における切削力の背分力の大きさの相関値である第一参照値と、凸歯７０を構成し第一歯面７１の裏面に位置する第二歯面７２における切削力の背分力の大きさの相関値である第二参照値との差を推定し（Ｓ１３）、第一参照値と第二参照値との差ΔＶが所定範囲内となるギヤスカイビングカッタＴの諸元を決定し（Ｓ１４）、決定された諸元となるギヤスカイビングカッタＴを用いて工作物Ｗを加工する（Ｓ１８）。【選択図】図１１
