The effectiveness of the optical method for evaluating engineering surfaces is described in terms of fluctuation properties as a means of a more global measuring technique of products. This is based on the 1/f fluctuation in which the power spectral density is proportional to the inverse of frequency f. Turned surfaces machined under different cutting conditions are tested by the reflection technique of a laser light, and its reflection intensity is analyzed to obtain the relation between the power spectral density and the spatial frequency. As a consequence, surface profiles with 1/f and 1/f1.5 properties seem to be satisfactory in conjunction with the results of sensory evaluation.
