る。<Prior art> A pinion cutter, which is one of the gear cutting tools used for cutting gears, is shaped like a gear and has a blade attached to one end of its seven teeth. By reciprocating in the axial direction, the locus of the cutting blade gives a synchronized rotation so that the virtual gear and the workpiece mesh and move, thereby cutting the tooth surface of the workpiece.Then, as the machining process progresses, the distance between the axes changes in the radial direction. The feed is applied so that the tooth thickness becomes shorter, and the generating movement is performed until the workpiece finally reaches the regular tooth thickness.

。In addition, when creating tooth profiles of different shapes on one workpiece, as shown in Fig. 6, pinion cutters 1 and 2 with different tooth profile shapes are superimposed coaxially and the pinion cutters 1 and 2 are rotated. The combined pinion cutter 3 is attached to a gear shaper to create tooth profiles of different shapes on the workpiece. By using the combination pinion cutter 3 in this way, it is possible to reduce the process complexity by only having to install the stem only once.<Problems to be Solved by the Invention> However, in the combination pinion cutter 3 described above, teeth,
Because the binion cutters 1 and 2 are coaxially stacked, the cutter length l becomes long, and when the cutter length l becomes long, various restrictions arise, such as the possibility of machining being impossible when machining stepped gears, etc. Put it away. As a result, stepped gears and the like having tooth profiles of different shapes are processed by attaching a plurality of pinion cutters one by one to a gear shaper, resulting in poor workability and poor processing accuracy.
