Abstract: Methods of machining a component including multiple dissimilar materials are disclosed. One method may include making a first cut in the component to remove at least a portion of a hardest material in the component and making a second cut in the component along a second cutting-path that does not include the hardest material. The first cut may expose a cut surface in the component and the second cut may extend through the cut surface. The cuts may be made using a turning operation and different cutting tools may be used for the first and second cuts. The hardest material may have a hardness of at least 50 HRC and the remaining materials may have a hardness of at most 45 HRC. The disclosed methods may be used to form a thrust face surface in a shell and sun gear assembly to extend tool life and reduce scrap.
