A computing system, method, and computer program product facilitates data mining of information, for example image data, relating to a surface of a manufactured product when the manufactured product is processed using a tool relative to which the manufactured product may be randomly oriented. For each manufactured object, data pertaining to the surface is converted into a weight distribution. A rotational axis along which each surface would tend to rotate under the action of gravity with the surface supported at its geometric centroid is determined. The sets of data can then be properly oriented relative to one another for data mining by aligning the rotational axis of each set of data.
