Abstract
Contours of a surface of a bearing which extends about an axis are displayed on a grid. To visualize the contours, points on the surface are measured at a plurality of angular positions to determine the corresponding measured values. The measured values at each angular position are normalized to determine a normalized measurement datum corresponding to each angular position. The normalized measurement datum is subtracted from each of the measured values to determine a plurality of deviations of the corresponding points. Shades are assigned that correspond to a range of possible deviations. Each of the deviations are displayed as a data segment on a grid that represents the shape of the surface of the bearing. Each data segment is shaded on the grid to the corresponding shade to provide a topographical representation of the contours of the surface of the bearing.
