This paper presents research results on the relationships between surface roughness and lightness of the surfaces machined by polishing, grinding, turning, and milling. The objective of this study is to investigate the correlation between surface roughness heights and lightness values measured on various material surfaces machined by the four processes. This may provide a fast and cost effective method for surface texture characterization. The four processes were chosen based on their distinct differences in the surface roughness values they produce. Some linear relationships were obtained for the surface roughness and lightness values.
