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.
