Recent Developments in Spline and Gear Cutting and Finishing 380118

DEVELOPMENTS in spline and gear cutting discussed in this paper include actual production results in climb-hobbing of splines and experimental results in climb-hobbing of gears. “Climb-hobbing” is defined as that method of hobbing wherein the cutting action starts at the surface of the part being hobbed and ends at the root of the spline or tooth - the direct opposite of the conventional method. Important advantages claimed for the method are a superior finish, increase in hob life, and lower power consumption.
Finishing-process developments considered are finish-cutting, burnishing, shaving, and grinding.
