Abstract
Official abstract text for this publication.
A method of manufacturing a gear-cutting tool is disclosed. The gear-cutting tool includes a base portion and cutter teeth extended from the base portion. Each cutter tooth includes a cutting tip portion. The method initiates with hardening the gear-cutting tool with a first hardening process. Thereafter, coating the cutter teeth with a wear resistant material and then hardening the cutting tip portion of each of the cutter teeth with a second hardening process. In the second hardening process, the heat treat is directed to penetrate through the wear resistant material. This process imparts the heat treatment to the wear resistant material and the cutting tip portion of the cutter teeth of the gear-cutting tool.
First claim
