Paper Abstract

The roughness parameters of diamond-turned surfaces are obtained from the Fourier transform of scattered light intensity. Theoretical consideration of the scattered intensity and its Fourier transform is made. It is shown that the Fourier transform of the scattered intensity is equivalent to the autocorrelation of the surface. From this autocorrelation function, we can derive the amplitude and frequency of the periodic tool marks, and the rms roughness and correlation length of the random surface component. Some experimental results for diamond turned aluminum metal surfaces are also given. The comparison of the light scattering data and stylus measurement is made. It shows a qualitative agreement.
