Abstract

This work deals with the determination of the parameters that have influence in the scanning of parts with different surface roughness. A commercial laser stripe system has been used for capturing points on a part surface by means of triangulation techniques. The parameters which can be affected by the roughness surface are first analyzed in order to establish the optimal conditions for the scanning tests. This way, gauges with different roughness grades and manufactured by different processing technologies have been tested. Since the roughness gauges were flat, the set of points captured onto a plane as well as their spatial dispersion with regard to the best-fit plane have been used as indicators of quality of the scanning process. The results of the tests provide some recommendations about the methodology and working conditions for scanning each type of surface.
