Abstract

This paper deals with a basic research on an on-line monitoring of surface roughness by using laser. The relation between an intensity distribution of the reflected laser light and the surface profile is studied. A function of the processed r.m.s. roughness is used, which is taken from the spatial filtering of the surface profile measured by stylus method. An experiment was carried out by using a rolled metallic sheet and pieces finished by an electrical discharge machine. The results show that the intensity distribution is approximately proportional to the r.m.s. roughness of a certain filterd surface profile. The experimental results are proved to be reasonable by theoretical analysis.
