Abstract

A method for qualifying a manufacturing process for a first component including a common geometric feature includes obtaining manufacturing data for the common geometric feature. The manufacturing data is associated with one or more qualified second components. The one or more qualified second components are different than the first component. Each of the one or more qualified second components include the common geometric feature. The method further includes modeling the manufacturing process for the common geometric feature of the one or more qualified second components using the manufacturing data, modeling the manufacturing process for the common geometric feature of the first component, obtaining manufacturing process parameters for the manufacturing process for the common geometric feature of the one or more qualified second components, and qualifying the manufacturing process for the common geometric feature of the first component.
