1. A method comprising:
- monitoring, by a computing device, horsepower of a machine tool used to machine a component during machining of a feature in the component with the machine tool;
determining a quality of the feature based on at least one of maximum horsepower, variation between maximum and minimum horsepower, or frequency of horsepower variation;
in response to determining that the quality of the feature is outside a predetermined tolerance range, selecting the feature for evaluation by an imaging device;
obtaining an image of the feature with an imaging device;
applying, by the computing device, principle component analysis (PCA) to the image of the feature;
ranking, by the computing device, the image of the feature relative to defined rankings of database images of similar features based on the PCA;
determining, by the computing device, whether the feature in the component includes white layer damage based on the ranking; and
presenting, by the computing device, via a user interface, an indication of whether the feature includes white layer damage in combination with a unique identifier for the feature.

Abstract
A method includes obtaining an image of a feature machined in a component with an imaging device, determining, by a computing device, a quality of the feature in the component based on the image of the feature, and storing, by the computing device, an indication of the quality of the feature in combination with a unique identifier for the feature in a non-transitory computer-readable medium.

6. A system for evaluating a quality of a feature machined in a component, the system comprising:
-
an imaging device; and a computing device, wherein the computing device is configured to; monitor horsepower of a machine tool used to machine the component during machining of the feature in the component with the machine tool; determine a quality of the feature based on at least one of maximum horsepower, variation between maximum and minimum horsepower, or frequency of horsepower variation; in response to determining that the quality of the feature is outside a predetermined tolerance range, select the feature for evaluation by the imaging device; send control signals that cause the imaging device to capture an image of the feature; apply principle component analysis (PCA) to the image of the feature; rank the image of the feature relative to define rankings of database images of similar features based on the PCA; determine whether the feature in the component includes white layer damage based on the ranking; and present, via a user interface, an indication of whether the feature includes white layer damage in combination with a unique identifier for the feature. - View Dependent Claims (7, 8, 9, 10, 11)

12. A non-transitory computer-readable data storage medium having instructions stored thereon that, when executed by one or more processors of a computing device, cause the computing device to:
-
monitor horsepower of a machine tool used to machine a component during machining of the feature in the component with the machine tool; determine a quality of the feature based on at least one of maximum horsepower, variation between maximum and minimum horsepower, or frequency of horsepower variation; in response to determining that the quality of the feature is outside a predetermined tolerance range, select the feature for evaluation by the imaging device; send control signals to an imaging device that cause the imaging device to capture an image of the feature; apply principle component analysis (PCA) to the image of the feature; rank the image of the feature relative to defined rankings of database images of similar features based on the PCA; determining whether the feature in the component includes white layer damage based on the ranking; and present, via a user interface, an indication of whether the feature includes white layer damage in combination with a unique identifier for the feature. - View Dependent Claims (13, 14)
