ABSTRACT:
In a method of producing splines on a shaft, cold deformation without removal of chips is effected on the outside face of a small-thickness tube in a single operation. The cold deformation includes hammering the small-thickness tube by a conjugate and simultaneous action of beating and kneading. The depth of the splines can be as much as half the thickness of the tube.
