This paper presents the quantitative relationship between one's visual estimation and the analytical data of the high quality surface texture. The quality of belt sanded surface is investigated systematically by 50 panelers. The test pieces are ground under the various grinding conditions using the platen type belt grinder. The results of factor analysis point out clearly that there are strong relationships between high quality and the properties of surface geometry based on the correlation diagram. The physical meaning of high quality estimation are explained by the range of (1) mean curvature, (2) mean slope of asperity, (3) optical characteristic roughness S_N, (4) center-line average height Ra, (5) the number of peaks, and (6) the number of zero-crossings, respectively. It was found that the irregularity of long crestedness perpendicular to grinding direction can be estimated by ARMA (4,3) model of S_N due to 0.2 mm beam.
