ABSTRACT:
An improved spline rack for use on a spline rack cutter is disclosed wherein the spline rack includes a plurality of teeth each having a top land surface that curves toward the inner tooth edge region, and the inner tooth edge region of each tooth includes a chamfer connecting the inner tooth edge region with the curved portion of the top land surface. In this manner, the exit radius of curvature of the inner top land surface may be maximized, while the chamfer prevents interference between the inner tooth edge region and the workpiece. A method of forming an improved spline rack is also disclosed.
