Abstract

A method directed to gear cutting tools and gear cutter job consolidation resulting in a single cutter capable of cutting a plurality of different members of a part family. The method comprises a multi-step approach comprising a first step of defining a temporary master. A second step creates a virtual master which is especially well-suited for accommodating the requirements of the jobs in the consolidation variety. A third step determines cutting depths and optimized machine settings for all consolidation jobs using the virtual master.

First claim

What is claimed is:

1. A method of manufacturing a gear cutting tool for cutting bevel and hypoid gears comprising one or more cutting blades with said cutting blades being configured whereby said gear cutting tool is operable for machining a plurality of gear design jobs for producing gears having different tooth geometries, said method comprising:
defining a temporary master cutter wherein said temporary master cutter is defined by one of the jobs that cuts the smallest root slot width of all of said plurality of gear design jobs,
defining a virtual master cutter representing a consolidation of the requirements of the jobs in said plurality of gear design jobs,
providing data representative of each of said plurality of gear design jobs, said data being dependent upon said virtual master cutter,
machining said one or more cutting blades of said gear cutting tool based on said data whereby said cutting tool is capable of producing said plurality of gear design jobs,
said machined one or more cutting blades having a different blade geometry than cutting blades of specific individual cutting tools that would be necessary to separately cut each respective member of said plurality of gear design jobs.

2. The method of claim 1 wherein said plurality of gear design jobs are pinions.

3. The method of claim 1 wherein said plurality of gear design jobs are ring gears.

4. The method of claim 1 wherein a temporary master cutter for a pinion is different than a temporary master cutter for a ring gear.

5. The method of claim 1 wherein said virtual master cutter comprises parameters different than specific individual cutting tools that would be necessary to separately cut each respective member of said plurality of gear design jobs.
