Using 3D non-contact profilometry for evaluating wear tracks

Résumé

This paper presents a new method for evaluating wear tracks with the help of 3D profilometry. Using a non-contact profilometer, every wear track and its surrounding zones are recorded as a matrix, each element being given as z(x, y), z being the height of the surface in the point characterized by the position (x, y). It is described a method of identifying the limits of the wear track based on curvature radii variation, characterizing each line recorded by the profilometer. The designed pseudo code provides accurate values for the wear track area and volume.
