The angular distributions of reflected light from specular and indecent metal-surfaces finished by diamond cutting tools are measured by an automatic recording goniophotometer. The results are compared with the diffraction theory of optical gratings with triangular grooves with two flat faces, and the difference is discussed in connection with irregularity of the side faces of grooves on the surfaces.
On both sides of the grooves on iridescent surfaces, there are many fine streaks parallel to the grooves which seem to be caused by unevenness of cutting edges of diamond tools. On other hand, the cutting edges of tools for specular surfaces are flat, and the distribution curves of reflected light correspond to the results calculated with diffraction theory fairly well.
