QUANTITATIVE ANALYSIS OF THE EFFECT OF THE COLOR AND ROUGHNESS WITH SIMPLE TEXTURE ON THE EVALUATION OF ROUGHNESS

Abstract

The purpose of this study is to do the quantitative explanation of the effect of the surface color and roughness on the evaluation of roughness(ROUGHNESS). By the relationship between ROUGHNESS and its color, the following was clarified. ROUGHNESS was most effected by its value. The lower the value was, the higher ROUGHNESS point was. Next, with the relationship that had been clarified previously between the surface roughness of sand-papers and its ROUGHNESS, some formulas which estimate ROUGHNESS of simple texture were derived from the relationship among ROUGHNESS, its surface roughness and its color.
