Shape Deviation

The parameters of shape difference are calculated for the girdle projection on the table plane relative to a given ideal girdle shape (ReferenceShape).

To achieve this, the minimum distance from each point on the girdle contour to the ideal shape contour is determined.

If a point from the ReferenceShape lies within the projection, the distance is positive; if it lies outside, the distance is negative.

Then, using a scanning window (with sizes of 11.25, 22.5, 45, 90, and 360 degrees) in azimuth, we calculate the maximum distance difference within the window.

For example, here is the result for a 22.5-degree window:

We output the values in mm and % relative to the Width, mm in bookmarks:
